+ ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^
+  NOTES:
+    1.  USE THE DEBUG DLL TO ENABLE PARAMETER VALIDATION VIA ASSERTS!
+        Here's how:
+        Copy X3DAudioDX_X.dll to where your application exists.
+        The debug DLL can be found under %WINDIR%\system32.
+        Rename X3DAudioDX_X.dll to X3DAudioX_X.dll to use the debug version.
+
+        Only parameters required by DSP settings being calculated as
+        stipulated by the calculation control flags are validated.
+
+    2.  Definition of terms:
+            LFE: Low Frequency Effect -- always omnidirectional.
+            LPF: Low Pass Filter, divided into two classifications:
+                 Direct -- Applied to the direct signal path,
+                           used for obstruction/occlusion effects.
+                 Reverb -- Applied to the reverb signal path,
+                           used for occlusion effects only.
+
+    3.  Volume level is expressed as a linear amplitude scaler:
+        1.0f represents no attenuation applied to the original signal,
+        0.5f denotes an attenuation of 6dB, and 0.0f results in silence.
+        Amplification (volume > 1.0f) is also allowed, and is not clamped.
+
+        LPF values range from 1.0f representing all frequencies pass through,
+        to 0.0f which results in silence as all frequencies are filtered out.
+
+    4.  X3DAudio uses a left-handed Cartesian coordinate system with values
+        on the x-axis increasing from left to right, on the y-axis from
+        bottom to top, and on the z-axis from near to far.
+        Azimuths are measured clockwise from a given reference direction.
+
+        Distance measurement is with respect to user-defined world units.
+        Applications may provide coordinates using any system of measure
+        as all non-normalized calculations are scale invariant, with such
+        operations natively occurring in user-defined world unit space.
+        Metric constants are supplied only as a convenience.
+        Distance is calculated using the Euclidean norm formula.
+
+    5.  Only real values are permissible with functions using 32-bit
+        float parameters -- NAN and infinite values are not accepted.
+        All computation occurs in 32-bit precision mode.                    */

+//                 The cone originates from the emitter base position,

+  NOTES:
+    1.  Definition of terms:
+            DSP: Digital Signal Processing.
+
+            CBR: Constant BitRate -- DSP that consumes a constant number of
+                 input samples to produce an output sample.
+                 For example, a 22kHz to 44kHz resampler is CBR DSP.
+                 Even though the number of input to output samples differ,
+                 the ratio between input to output rate remains constant.
+                 All user-defined XAPOs are assumed to be CBR as
+                 XAudio2 only allows CBR DSP to be added to an effect chain.
+
+            XAPO: Cross-platform Audio Processing Object --
+                  a thin wrapper that manages DSP code, allowing it
+                  to be easily plugged into an XAudio2 effect chain.
+
+            Frame: A block of samples, one per channel,
+                   to be played simultaneously.
+
+            In-Place: Processing such that the input buffer equals the
+                      output buffer (i.e. input data modified directly).
+                      This form of processing is generally more efficient
+                      than using separate memory for input and output.
+                      However, an XAPO may not perform format conversion
+                      when processing in-place.
+
+    2.  XAPO member variables are divided into three classifications:
+            Immutable: Set once via IXAPO::Initialize and remain
+                       constant during the lifespan of the XAPO.
+
+            Locked: May change before the XAPO is locked via
+                    IXAPO::LockForProcess but remain constant
+                    until IXAPO::UnlockForProcess is called.
+
+            Dynamic: May change from one processing pass to the next,
+                     usually via IXAPOParameters::SetParameters.
+                     XAPOs should assign reasonable defaults to their dynamic
+                     variables during IXAPO::Initialize/LockForProcess so
+                     that calling IXAPOParameters::SetParameters is not
+                     required before processing begins.
+
+        When implementing an XAPO, determine the type of each variable and
+        initialize them in the appropriate method.  Immutable variables are
+        generally preferable over locked which are preferable over dynamic.
+        That is, one should strive to minimize XAPO state changes for
+        best performance, maintainability, and ease of use.
+
+    3.  To minimize glitches, the realtime audio processing thread must
+        not block.  XAPO methods called by the realtime thread are commented
+        as non-blocking and therefore should not use blocking synchronization,
+        allocate memory, access the disk, etc.  The XAPO interfaces were
+        designed to allow an effect implementer to move such operations
+        into other methods called on an application controlled thread.
+
+    4.  Extending functionality is accomplished through the addition of new
+        COM interfaces.  For example, if a new member is added to a parameter
+        structure, a new interface using the new structure should be added,
+        leaving the original interface unchanged.
+        This ensures consistent communication between future versions of
+        XAudio2 and various versions of XAPOs that may exist in an application.
+
+    5.  All audio data is interleaved in XAudio2.
+        The default audio format for an effect chain is WAVE_FORMAT_IEEE_FLOAT.
+
+    6.  User-defined XAPOs should assume all input and output buffers are
+        16-byte aligned.
+
+    7.  See XAPOBase.h for an XAPO base class which provides a default
+        implementation for most of the interface methods defined below.     */

+// Aligned Matrices
+//
+// This class helps keep matrices 16-byte aligned as preferred by P4 cpus.
+// It aligns matrices on the stack and on the heap or in global scope.
+// It does this using __declspec(align(16)) which works on VC7 and on VC 6
+// with the processor pack. Unfortunately there is no way to detect the 
+// latter so this is turned on only on VC7. On other compilers this is the
+// the same as D3DXMATRIX.
+//
+// Using this class on a compiler that does not actually do the alignment
+// can be dangerous since it will not expose bugs that ignore alignment.
+// E.g if an object of this class in inside a struct or class, and some code
+// memcopys data in it assuming tight packing. This could break on a compiler
+// that eventually start aligning the matrix.

+
+// This function creates atlases for meshes. There are two modes of operation,
+// either based on the number of charts, or the maximum allowed stretch. If the
+// maximum allowed stretch is 0, then each triangle will likely be in its own
+// chart.
+
+//
+// The parameters are as follows:
+//  pMesh - Input mesh to calculate an atlas for. This must have a position
+//          channel and at least a 2-d texture channel.
+//  uMaxChartNumber - The maximum number of charts required for the atlas.
+//                    If this is 0, it will be parameterized based solely on
+//                    stretch.
+//  fMaxStretch - The maximum amount of stretch, if 0, no stretching is allowed,
+//                if 1, then any amount of stretching is allowed.
+//  uWidth - The width of the texture the atlas will be used on.
+//  uHeight - The height of the texture the atlas will be used on.
+//  fGutter - The minimum distance, in texels between two charts on the atlas.
+//            this gets scaled by the width, so if fGutter is 2.5, and it is
+//            used on a 512x512 texture, then the minimum distance will be
+//            2.5 / 512 in u-v space.
+//  dwTextureIndex - Specifies which texture coordinate to write to in the
+//                   output mesh (which is cloned from the input mesh). Useful
+//                   if your vertex has multiple texture coordinates.
+//  pdwAdjacency - a pointer to an array with 3 DWORDs per face, indicating
+//                 which triangles are adjacent to each other.
+//  pdwFalseEdgeAdjacency - a pointer to an array with 3 DWORDS per face, indicating
+//                          at each face, whether an edge is a false edge or not (using
+//                          the same ordering as the adjacency data structure). If this
+//                          is NULL, then it is assumed that there are no false edges. If
+//                          not NULL, then a non-false edge is indicated by -1 and a false
+//                          edge is indicated by any other value (it is not required, but
+//                          it may be useful for the caller to use the original adjacency
+//                          value). This allows you to parameterize a mesh of quads, and
+//                          the edges down the middle of each quad will not be cut when
+//                          parameterizing the mesh.
+//  pfIMTArray - a pointer to an array with 3 FLOATs per face, describing the
+//               integrated metric tensor for that face. This lets you control
+//               the way this triangle may be stretched in the atlas. The IMT
+//               passed in will be 3 floats (a,b,c) and specify a symmetric
+//               matrix (a b) that, given a vector (s,t), specifies the 
+//                      (b c)
+//               distance between a vector v1 and a vector v2 = v1 + (s,t) as
+//               sqrt((s, t) * M * (s, t)^T).
+//               In other words, this lets one specify the magnitude of the
+//               stretch in an arbitrary direction in u-v space. For example
+//               if a = b = c = 1, then this scales the vector (1,1) by 2, and
+//               the vector (1,-1) by 0. Note that this is multiplying the edge
+//               length by the square of the matrix, so if you want the face to
+//               stretch to twice its
+//               size with no shearing, the IMT value should be (2, 0, 2), which
+//               is just the identity matrix times 2.
+//               Note that this assumes you have an orientation for the triangle
+//               in some 2-D space. For D3DXUVAtlas, this space is created by
+//               letting S be the direction from the first to the second
+//               vertex, and T be the cross product between the normal and S.
+//               
+//  pStatusCallback - Since the atlas creation process can be very CPU intensive,
+//                    this allows the programmer to specify a function to be called
+//                    periodically, similarly to how it is done in the PRT simulation
+//                    engine.
+//  fCallbackFrequency - This lets you specify how often the callback will be
+//                       called. A decent default should be 0.0001f.
+//  pUserContext - a void pointer to be passed back to the callback function
+//  dwOptions - A combination of flags in the D3DXUVATLAS enum
+//  ppMeshOut - A pointer to a location to store a pointer for the newly created
+//              mesh.
+//  ppFacePartitioning - A pointer to a location to store a pointer for an array,
+//                       one DWORD per face, giving the final partitioning
+//                       created by the atlasing algorithm.
+//  ppVertexRemapArray - A pointer to a location to store a pointer for an array,
+//                       one DWORD per vertex, giving the vertex it was copied
+//                       from, if any vertices needed to be split.
+//  pfMaxStretchOut - A location to store the maximum stretch resulting from the
+//                    atlasing algorithm.
+//  puNumChartsOut - A location to store the number of charts created, or if the
+//                   maximum number of charts was too low, this gives the minimum

+// D3DXSHADER_DEBUG
+//   Insert debug file/line/type/symbol information.
+//
+// D3DXSHADER_SKIPVALIDATION
+//   Do not validate the generated code against known capabilities and
+//   constraints.  This option is only recommended when compiling shaders
+//   you KNOW will work.  (ie. have compiled before without this option.)
+//   Shaders are always validated by D3D before they are set to the device.
+//
+// D3DXSHADER_SKIPOPTIMIZATION 
+//   Instructs the compiler to skip optimization steps during code generation.
+//   Unless you are trying to isolate a problem in your code using this option 
+//   is not recommended.
+//
+// D3DXSHADER_PACKMATRIX_ROWMAJOR
+//   Unless explicitly specified, matrices will be packed in row-major order
+//   on input and output from the shader.
+//
+// D3DXSHADER_PACKMATRIX_COLUMNMAJOR
+//   Unless explicitly specified, matrices will be packed in column-major 
+//   order on input and output from the shader.  This is generally more 
+//   efficient, since it allows vector-matrix multiplication to be performed
+//   using a series of dot-products.
+//
+// D3DXSHADER_PARTIALPRECISION
+//   Force all computations in resulting shader to occur at partial precision.
+//   This may result in faster evaluation of shaders on some hardware.
+//
+// D3DXSHADER_FORCE_VS_SOFTWARE_NOOPT
+//   Force compiler to compile against the next highest available software
+//   target for vertex shaders.  This flag also turns optimizations off, 
+//   and debugging on.  
+//
+// D3DXSHADER_FORCE_PS_SOFTWARE_NOOPT
+//   Force compiler to compile against the next highest available software
+//   target for pixel shaders.  This flag also turns optimizations off, 
+//   and debugging on.
+//
+// D3DXSHADER_NO_PRESHADER
+//   Disables Preshaders. Using this flag will cause the compiler to not 
+//   pull out static expression for evaluation on the host cpu
+//
+// D3DXSHADER_AVOID_FLOW_CONTROL

+//  D3DX_FILTER_TRIANGLE
+//      Every pixel in the source image contributes equally to the

+// -------------------------------------------------------------------------------
+// Introduction
+//
+// rpcsal.h provides a set of annotations to describe how RPC functions use their
+// parameters - the assumptions it makes about them, adn the guarantees it makes 
+// upon finishing.  These annotations are similar to those found in specstrings.h,
+// but are designed to be used by the MIDL compiler when it generates annotations
+// enabled header files.
+//
+// IDL authors do not need to annotate their functions declarations.  The MIDL compiler
+// will interpret the IDL directives and use one of the annotations contained 
+// in this header.  This documentation is intended to help those trying to  understand 
+// the MIDL-generated header files or those who maintain their own copies of these files.
+//
+// -------------------------------------------------------------------------------
+// Differences between rpcsal.h and specstrings.h
+// 
+// There are a few important differences between the annotations found in rpcsal.h and
+// those in specstrings.h:
+// 
+// 1. [in] parameters are not marked as read-only.  They may be used for scratch space 
+// at the server and changes will not affect the client.
+// 2. String versions of each macro alleviates the need for a special type definition
+//
+// -------------------------------------------------------------------------------
+// Interpreting RPC Annotations
+//
+// These annotations are interpreted precisely in the same way as those in specstrings.h.  
+// Please refer to that header for information related to general usage in annotations. 
+//
+// To construct an RPC annotation, concatenate the appropriate value from each category
+// along with a leading __RPC_.  A typical annotation looks like "__RPC__in_string".
+//

+//
+// Level: Describes the buffer pointer's level of indirection from the parameter or
+//          return value 'p'.
+//
+// <>         : p is the buffer pointer.
+// _deref     : *p is the buffer pointer. p must not be NULL.
+// _deref_opt : *p may be the buffer pointer. p may be NULL, in which case the rest of
+//                the annotation is ignored.
+//
+// Usage: Describes how the function uses the buffer.
+//
+// <>     : The buffer is not accessed. If used on the return value or with _deref, the
+//            function will provide the buffer, and it will be uninitialized at exit.
+//            Otherwise, the caller must provide the buffer. This should only be used
+//            for alloc and free functions.
+// _in    : The function will only read from the buffer. The caller must provide the
+//            buffer and initialize it. Cannot be used with _deref.
+// _out   : The function will only write to the buffer. If used on the return value or
+//            with _deref, the function will provide the buffer and initialize it.
+//            Otherwise, the caller must provide the buffer, and the function will
+//            initialize it.
+// _inout : The function may freely read from and write to the buffer. The caller must
+//            provide the buffer and initialize it. If used with _deref, the buffer may
+//            be reallocated by the function.
+//
+// Size: Describes the total size of the buffer. This may be less than the space actually
+//         allocated for the buffer, in which case it describes the accessible amount.
+//
+// <>      : No buffer size is given. If the type specifies the buffer size (such as
+//             with LPSTR and LPWSTR), that amount is used. Otherwise, the buffer is one
+//             element long. Must be used with _in, _out, or _inout.
+// _ecount : The buffer size is an explicit element count.
+// _bcount : The buffer size is an explicit byte count.
+//
+// Output: Describes how much of the buffer will be initialized by the function. For
+//           _inout buffers, this also describes how much is initialized at entry. Omit this
+//           category for _in buffers; they must be fully initialized by the caller.
+//
+// <>    : The type specifies how much is initialized. For instance, a function initializing
+//           an LPWSTR must NULL-terminate the string.
+// _full : The function initializes the entire buffer.
+// _part : The function initializes part of the buffer, and explicitly indicates how much.
+//
+// Optional: Describes if the buffer itself is optional.
+//
+// <>   : The pointer to the buffer must not be NULL.
+// _opt : The pointer to the buffer might be NULL. It will be checked before being dereferenced.
+//
+// String: Describes if the buffer is NULL terminated
+//
+// <>      : The buffer is not assumed to be NULL terminated
+// _string : The buffer is assumed to be NULL terminated once it has been initialized
+//
+// Parameters: Gives explicit counts for the size and length of the buffer.
+//
+// <>            : There is no explicit count. Use when neither _ecount nor _bcount is used.
+// (size)        : Only the buffer's total size is given. Use with _ecount or _bcount but not _part.
+// (size,length) : The buffer's total size and initialized length are given. Use with _ecount_part
+//                   and _bcount_part.
+//
+// Notes:
+//
+// 1. Specifying two buffer annotations on a single parameter results in unspecified behavior
+//    (e.g. __RPC__in_bcount(5) __RPC__out_bcount(6)
+// 
+// 2. The size of the buffer and the amount that has been initialized are separate concepts.  
+//    Specify the size using _ecount or _bcount.  Specify the amount that is initialized using 
+//    _full, _part, or _string.  As a special case, a single element buffer does not need 
+//    _ecount, _bcount, _full, or _part
+// 
+// 3. The count may be less than the total size of the buffer in which case it describes the 
+//    accessible portion. 
+// 
+// 4. "__RPC__opt" and "__RPC_deref" are not valid annotations.
+// 
+// 5. The placement of _opt when using _deref is important:
+//      __RPC__deref_opt_...      : Input may be NULL
+//      __RPC__deref_..._opt      : Output may be NULL
+//      __RPC__deref_opt_..._opt  : Both input and output may be NULL

+ ***************************************************************************/
+
+// A typical XMA2 file contains these RIFF chunks:
+//
+// 'fmt' or 'XMA2' chunk (or both): A description of the XMA data's structure
+// and characteristics (length, channels, sample rate, loops, block size, etc).
+//
+// 'seek' chunk: A seek table to help navigate the XMA data.
+//
+// 'data' chunk: The encoded XMA2 data.
+//
+// The encoded XMA2 data is structured as a set of BLOCKS, which contain PACKETS,
+// which contain FRAMES, which contain SUBFRAMES (roughly speaking).  The frames
+// in a file may also be divided into several subsets, called STREAMS.
+//
+// FRAME: A variable-sized segment of XMA data that decodes to exactly 512 mono
+//      or stereo PCM samples.  This is the smallest unit of XMA data that can
+//      be decoded in isolation.  Frames are an arbitrary number of bits in
+//      length, and need not be byte-aligned.  See "XMA frame structure" below.
+//
+// SUBFRAME: A region of bits in an XMA frame that decodes to 128 mono or stereo
+//      samples.  The XMA decoder cannot decode a subframe in isolation; it needs
+//      a whole frame to work with.  However, it can begin emitting the frame's
+//      decoded samples at any one of the four subframe boundaries.  Subframes
+//      can be addressed for seeking and looping purposes.
+//
+// PACKET: A 2Kb region containing a 32-bit header and some XMA frames.  Frames
+//      can (and usually do) span packets.  A packet's header includes the offset
+//      in bits of the first frame that begins within that packet.  All of the
+//      frames that begin in a given packet belong to the same "stream" (see the
+//      Multichannel Audio section below).
+//
+// STREAM: A set of packets within an XMA file that all contain data for the
+//      same mono or stereo component of a PCM file with more than two channels.
+//      The packets comprising a given stream may be interleaved with each other
+//      more or less arbitrarily; see Multichannel Audio.
+//
+// BLOCK: An array of XMA packets; or, to break it down differently, a series of
+//      consecutive XMA frames, padded at the end with reserved data.  A block
+//      must contain at least one 2Kb packet per stream, and it can hold up to
+//      4095 packets (8190Kb), but its size is typically in the 32Kb-128Kb range.
+//      (The size chosen involves a trade-off between memory use and efficiency
+//      of reading from permanent storage.)
+//
+//      XMA frames do not span blocks, so a block is guaranteed to begin with a
+//      set of complete frames, one per stream.  Also, a block in a multi-stream
+//      XMA2 file always contains the same number of samples for each stream;
+//      see Multichannel Audio.
+//
+// The 'data' chunk in an XMA2 file is an array of XMA2WAVEFORMAT.BlockCount XMA
+// blocks, all the same size (as specified in XMA2WAVEFORMAT.BlockSizeInBytes)
+// except for the last one, which may be shorter.
+
+
+// MULTICHANNEL AUDIO: the XMA decoder can only decode raw XMA data into either
+// mono or stereo PCM data.  In order to encode a 6-channel file (say), the file
+// must be deinterleaved into 3 stereo streams that are encoded independently,
+// producing 3 encoded XMA data streams.  Then the packets in these 3 streams
+// are interleaved to produce a single XMA2 file, and some information is added
+// to the file so that the original 6-channel audio can be reconstructed at
+// decode time.  This works using the concept of an XMA stream (see above).
+//
+// The frames for all the streams in an XMA file are interleaved in an arbitrary
+// order.  To locate a frame that belongs to a given stream in a given XMA block,
+// you must examine the first few packets in the block.  Here (and only here) the
+// packets are guaranteed to be presented in stream order, so that all frames
+// beginning in packet 0 belong to stream 0 (the first stereo pair), etc.
+//
+// (This means that when decoding multi-stream XMA files, only entire XMA blocks
+// should be submitted to the decoder; otherwise it cannot know which frames
+// belong to which stream.)
+//
+// Once you have one frame that belongs to a given stream, you can find the next
+// one by looking at the frame's 'NextFrameOffsetBits' value (which is stored in
+// its first 15 bits; see XMAFRAME below).  The GetXmaFrameBitPosition function
+// uses this technique.
+
+
+// SEEKING IN XMA2 FILES: Here is some pseudocode to find the byte position and
+// subframe in an XMA2 file which will contain sample S when decoded.
+//
+// 1. Traverse the seek table to find the XMA2 block containing sample S. The
+//    seek table is an array of big-endian DWORDs, one per block in the file.
+//    The Nth DWORD is the total number of PCM samples that would be obtained
+//    by decoding the entire XMA file up to the end of block N.  Hence, the
+//    block we want is the first one whose seek table entry is greater than S.
+//    (See the GetXmaBlockContainingSample helper function.)
+//
+// 2. Calculate which frame F within the block found above contains sample S.
+//    Since each frame decodes to 512 samples, this is straightforward.  The
+//    first frame in the block produces samples X to X + 512, where X is the
+//    seek table entry for the prior block.  So F is (S - X) / 512.
+//
+// 3. Find the bit offset within the block where frame F starts.  Since frames
+//    are variable-sized, this can only be done by traversing all the frames in
+//    the block until we reach frame F.  (See GetXmaFrameBitPosition.)
+//
+// 4. Frame F has four 128-sample subframes.  To find the subframe containing S,
+//    we can use the formula (S % 512) / 128.
+//
+// In the case of multi-stream XMA files, sample S is a multichannel sample with
+// parts coming from several frames, one per stream.  To find all these frames,
+// steps 2-4 need to be repeated for each stream N, using the knowledge that the
+// first packets in a block are presented in stream order.  The frame traversal
+// in step 3 must be started at the first frame in the Nth packet of the block,
+// which will be the first frame for stream N.  (And the packet header will tell
+// you the first frame's start position within the packet.)
+//
+// Step 1 can be performed using the GetXmaBlockContainingSample function below,
+// and steps 2-4 by calling GetXmaDecodePositionForSample once for each stream.

+ *
+ * The Opus codec is designed for interactive speech and audio transmission over the Internet.
+ * It is designed by the IETF Codec Working Group and incorporates technology from
+ * Skype's SILK codec and Xiph.Org's CELT codec.
+ *
+ * The Opus codec is designed to handle a wide range of interactive audio applications,
+ * including Voice over IP, videoconferencing, in-game chat, and even remote live music
+ * performances. It can scale from low bit-rate narrowband speech to very high quality
+ * stereo music. Its main features are:
+
+ * @li Sampling rates from 8 to 48 kHz
+ * @li Bit-rates from 6 kb/s to 510 kb/s
+ * @li Support for both constant bit-rate (CBR) and variable bit-rate (VBR)
+ * @li Audio bandwidth from narrowband to full-band
+ * @li Support for speech and music
+ * @li Support for mono and stereo
+ * @li Support for multichannel (up to 255 channels)
+ * @li Frame sizes from 2.5 ms to 60 ms
+ * @li Good loss robustness and packet loss concealment (PLC)
+ * @li Floating point and fixed-point implementation
+ *
+ * Documentation sections:

+/** @defgroup opus_encoder Opus Encoder
+  * @{
+  *
+  * @brief This page describes the process and functions used to encode Opus.
+  *
+  * Since Opus is a stateful codec, the encoding process starts with creating an encoder
+  * state. This can be done with:
+  *
+  * @code
+  * int          error;
+  * OpusEncoder *enc;
+  * enc = opus_encoder_create(Fs, channels, application, &error);
+  * @endcode
+  *
+  * From this point, @c enc can be used for encoding an audio stream. An encoder state
+  * @b must @b not be used for more than one stream at the same time. Similarly, the encoder
+  * state @b must @b not be re-initialized for each frame.
+  *
+  * While opus_encoder_create() allocates memory for the state, it's also possible
+  * to initialize pre-allocated memory:
+  *
+  * @code
+  * int          size;
+  * int          error;
+  * OpusEncoder *enc;
+  * size = opus_encoder_get_size(channels);
+  * enc = malloc(size);
+  * error = opus_encoder_init(enc, Fs, channels, application);
+  * @endcode
+  *
+  * where opus_encoder_get_size() returns the required size for the encoder state. Note that
+  * future versions of this code may change the size, so no assuptions should be made about it.
+  *
+  * The encoder state is always continuous in memory and only a shallow copy is sufficient
+  * to copy it (e.g. memcpy())
+  *
+  * It is possible to change some of the encoder's settings using the opus_encoder_ctl()
+  * interface. All these settings already default to the recommended value, so they should
+  * only be changed when necessary. The most common settings one may want to change are:
+  *
+  * @code
+  * opus_encoder_ctl(enc, OPUS_SET_BITRATE(bitrate));
+  * opus_encoder_ctl(enc, OPUS_SET_COMPLEXITY(complexity));
+  * opus_encoder_ctl(enc, OPUS_SET_SIGNAL(signal_type));
+  * @endcode
+  *
+  * where
+  *
+  * @arg bitrate is in bits per second (b/s)
+  * @arg complexity is a value from 1 to 10, where 1 is the lowest complexity and 10 is the highest
+  * @arg signal_type is either OPUS_AUTO (default), OPUS_SIGNAL_VOICE, or OPUS_SIGNAL_MUSIC
+  *
+  * See @ref opus_encoderctls and @ref opus_genericctls for a complete list of parameters that can be set or queried. Most parameters can be set or changed at any time during a stream.
+  *
+  * To encode a frame, opus_encode() or opus_encode_float() must be called with exactly one frame (2.5, 5, 10, 20, 40 or 60 ms) of audio data:
+  * @code
+  * len = opus_encode(enc, audio_frame, frame_size, packet, max_packet);
+  * @endcode
+  *
+  * where
+  * <ul>
+  * <li>audio_frame is the audio data in opus_int16 (or float for opus_encode_float())</li>
+  * <li>frame_size is the duration of the frame in samples (per channel)</li>
+  * <li>packet is the byte array to which the compressed data is written</li>
+  * <li>max_packet is the maximum number of bytes that can be written in the packet (4000 bytes is recommended).
+  *     Do not use max_packet to control VBR target bitrate, instead use the #OPUS_SET_BITRATE CTL.</li>
+  * </ul>
+  *
+  * opus_encode() and opus_encode_float() return the number of bytes actually written to the packet.
+  * The return value <b>can be negative</b>, which indicates that an error has occurred. If the return value
+  * is 2 bytes or less, then the packet does not need to be transmitted (DTX).
+  *
+  * Once the encoder state if no longer needed, it can be destroyed with
+  *
+  * @code
+  * opus_encoder_destroy(enc);
+  * @endcode
+  *
+  * If the encoder was created with opus_encoder_init() rather than opus_encoder_create(),
+  * then no action is required aside from potentially freeing the memory that was manually
+  * allocated for it (calling free(enc) for the example above)
+  *
+  */

+/** @defgroup opus_decoder Opus Decoder
+  * @{
+  *
+  * @brief This page describes the process and functions used to decode Opus.
+  *
+  * The decoding process also starts with creating a decoder
+  * state. This can be done with:
+  * @code
+  * int          error;
+  * OpusDecoder *dec;
+  * dec = opus_decoder_create(Fs, channels, &error);
+  * @endcode
+  * where
+  * @li Fs is the sampling rate and must be 8000, 12000, 16000, 24000, or 48000
+  * @li channels is the number of channels (1 or 2)
+  * @li error will hold the error code in case of failure (or #OPUS_OK on success)
+  * @li the return value is a newly created decoder state to be used for decoding
+  *
+  * While opus_decoder_create() allocates memory for the state, it's also possible
+  * to initialize pre-allocated memory:
+  * @code
+  * int          size;
+  * int          error;
+  * OpusDecoder *dec;
+  * size = opus_decoder_get_size(channels);
+  * dec = malloc(size);
+  * error = opus_decoder_init(dec, Fs, channels);
+  * @endcode
+  * where opus_decoder_get_size() returns the required size for the decoder state. Note that
+  * future versions of this code may change the size, so no assuptions should be made about it.
+  *
+  * The decoder state is always continuous in memory and only a shallow copy is sufficient
+  * to copy it (e.g. memcpy())
+  *
+  * To decode a frame, opus_decode() or opus_decode_float() must be called with a packet of compressed audio data:
+  * @code
+  * frame_size = opus_decode(dec, packet, len, decoded, max_size, 0);
+  * @endcode
+  * where
+  *
+  * @li packet is the byte array containing the compressed data
+  * @li len is the exact number of bytes contained in the packet
+  * @li decoded is the decoded audio data in opus_int16 (or float for opus_decode_float())
+  * @li max_size is the max duration of the frame in samples (per channel) that can fit into the decoded_frame array
+  *
+  * opus_decode() and opus_decode_float() return the number of samples (per channel) decoded from the packet.
+  * If that value is negative, then an error has occurred. This can occur if the packet is corrupted or if the audio
+  * buffer is too small to hold the decoded audio.
+  *
+  * Opus is a stateful codec with overlapping blocks and as a result Opus
+  * packets are not coded independently of each other. Packets must be
+  * passed into the decoder serially and in the correct order for a correct
+  * decode. Lost packets can be replaced with loss concealment by calling
+  * the decoder with a null pointer and zero length for the missing packet.
+  *
+  * A single codec state may only be accessed from a single thread at
+  * a time and any required locking must be performed by the caller. Separate
+  * streams must be decoded with separate decoder states and can be decoded
+  * in parallel unless the library was compiled with NONTHREADSAFE_PSEUDOSTACK
+  * defined.
+  *

+  * @{
+  *
+  * The repacketizer can be used to merge multiple Opus packets into a single
+  * packet or alternatively to split Opus packets that have previously been
+  * merged. Splitting valid Opus packets is always guaranteed to succeed,
+  * whereas merging valid packets only succeeds if all frames have the same
+  * mode, bandwidth, and frame size, and when the total duration of the merged
+  * packet is no more than 120 ms. The 120 ms limit comes from the
+  * specification and limits decoder memory requirements at a point where
+  * framing overhead becomes negligible.
+  *
+  * The repacketizer currently only operates on elementary Opus
+  * streams. It will not manipualte multistream packets successfully, except in
+  * the degenerate case where they consist of data from a single stream.
+  *
+  * The repacketizing process starts with creating a repacketizer state, either
+  * by calling opus_repacketizer_create() or by allocating the memory yourself,
+  * e.g.,
+  * @code
+  * OpusRepacketizer *rp;
+  * rp = (OpusRepacketizer*)malloc(opus_repacketizer_get_size());
+  * if (rp != NULL)
+  *     opus_repacketizer_init(rp);
+  * @endcode
+  *
+  * Then the application should submit packets with opus_repacketizer_cat(),
+  * extract new packets with opus_repacketizer_out() or
+  * opus_repacketizer_out_range(), and then reset the state for the next set of
+  * input packets via opus_repacketizer_init().
+  *
+  * For example, to split a sequence of packets into individual frames:
+  * @code
+  * unsigned char *data;
+  * int len;
+  * while (get_next_packet(&data, &len))
+  * {
+  *   unsigned char out[1276];
+  *   opus_int32 out_len;
+  *   int nb_frames;
+  *   int err;
+  *   int i;
+  *   err = opus_repacketizer_cat(rp, data, len);
+  *   if (err != OPUS_OK)
+  *   {
+  *     release_packet(data);
+  *     return err;
+  *   }
+  *   nb_frames = opus_repacketizer_get_nb_frames(rp);
+  *   for (i = 0; i < nb_frames; i++)
+  *   {
+  *     out_len = opus_repacketizer_out_range(rp, i, i+1, out, sizeof(out));
+  *     if (out_len < 0)
+  *     {
+  *        release_packet(data);
+  *        return (int)out_len;
+  *     }

+  *   }
+  *   opus_repacketizer_init(rp);
+  *   release_packet(data);
+  * }
+  * @endcode
+  *
+  * Alternatively, to combine a sequence of frames into packets that each
+  * contain up to <code>TARGET_DURATION_MS</code> milliseconds of data:
+  * @code
+  * // The maximum number of packets with duration TARGET_DURATION_MS occurs
+  * // when the frame size is 2.5 ms, for a total of (TARGET_DURATION_MS*2/5)
+  * // packets.
+  * unsigned char *data[(TARGET_DURATION_MS*2/5)+1];
+  * opus_int32 len[(TARGET_DURATION_MS*2/5)+1];
+  * int nb_packets;
+  * unsigned char out[1277*(TARGET_DURATION_MS*2/2)];
+  * opus_int32 out_len;
+  * int prev_toc;
+  * nb_packets = 0;

+/** @defgroup opus_custom Opus Custom
+  * @{
+  *  Opus Custom is an optional part of the Opus specification and
+  * reference implementation which uses a distinct API from the regular
+  * API and supports frame sizes that are not normally supported.\ Use
+  * of Opus Custom is discouraged for all but very special applications
+  * for which a frame size different from 2.5, 5, 10, or 20 ms is needed
+  * (for either complexity or latency reasons) and where interoperability
+  * is less important.
+  *
+  * In addition to the interoperability limitations the use of Opus custom
+  * disables a substantial chunk of the codec and generally lowers the
+  * quality available at a given bitrate. Normally when an application needs
+  * a different frame size from the codec it should buffer to match the
+  * sizes but this adds a small amount of delay which may be important
+  * in some very low latency applications. Some transports (especially
+  * constant rate RF transports) may also work best with frames of
+  * particular durations.
+  *
+  * Libopus only supports custom modes if they are enabled at compile time.
+  *
+  * The Opus Custom API is similar to the regular API but the
+  * @ref opus_encoder_create and @ref opus_decoder_create calls take
+  * an additional mode parameter which is a structure produced by
+  * a call to @ref opus_custom_mode_create. Both the encoder and decoder
+  * must create a mode using the same sample rate (fs) and frame size
+  * (frame size) so these parameters must either be signaled out of band
+  * or fixed in a particular implementation.
+  *
+  * Similar to regular Opus the custom modes support on the fly frame size
+  * switching, but the sizes available depend on the particular frame size in
+  * use. For some initial frame sizes on a single on the fly size is available.

+/** @defgroup opus_multistream Opus Multistream API
+  * @{
+  *
+  * The multistream API allows individual Opus streams to be combined into a
+  * single packet, enabling support for up to 255 channels. Unlike an
+  * elementary Opus stream, the encoder and decoder must negotiate the channel
+  * configuration before the decoder can successfully interpret the data in the
+  * packets produced by the encoder. Some basic information, such as packet
+  * duration, can be computed without any special negotiation.
+  *
+  * The format for multistream Opus packets is defined in
+  * <a href="https://tools.ietf.org/html/rfc7845">RFC 7845</a>
+  * and is based on the self-delimited Opus framing described in Appendix B of
+  * <a href="https://tools.ietf.org/html/rfc6716">RFC 6716</a>.
+  * Normal Opus packets are just a degenerate case of multistream Opus packets,
+  * and can be encoded or decoded with the multistream API by setting
+  * <code>streams</code> to <code>1</code> when initializing the encoder or
+  * decoder.
+  *
+  * Multistream Opus streams can contain up to 255 elementary Opus streams.
+  * These may be either "uncoupled" or "coupled", indicating that the decoder
+  * is configured to decode them to either 1 or 2 channels, respectively.
+  * The streams are ordered so that all coupled streams appear at the
+  * beginning.
+  *
+  * A <code>mapping</code> table defines which decoded channel <code>i</code>
+  * should be used for each input/output (I/O) channel <code>j</code>. This table is
+  * typically provided as an unsigned char array.
+  * Let <code>i = mapping[j]</code> be the index for I/O channel <code>j</code>.
+  * If <code>i < 2*coupled_streams</code>, then I/O channel <code>j</code> is
+  * encoded as the left channel of stream <code>(i/2)</code> if <code>i</code>
+  * is even, or  as the right channel of stream <code>(i/2)</code> if
+  * <code>i</code> is odd. Otherwise, I/O channel <code>j</code> is encoded as
+  * mono in stream <code>(i - coupled_streams)</code>, unless it has the special
+  * value 255, in which case it is omitted from the encoding entirely (the
+  * decoder will reproduce it as silence). Each value <code>i</code> must either
+  * be the special value 255 or be less than <code>streams + coupled_streams</code>.
+  *
+  * The output channels specified by the encoder
+  * should use the
+  * <a href="https://www.xiph.org/vorbis/doc/Vorbis_I_spec.html#x1-810004.3.9">Vorbis
+  * channel ordering</a>. A decoder may wish to apply an additional permutation
+  * to the mapping the encoder used to achieve a different output channel
+  * order (e.g. for outputing in WAV order).
+  *
+  * Each multistream packet contains an Opus packet for each stream, and all of
+  * the Opus packets in a single multistream packet must have the same
+  * duration. Therefore the duration of a multistream packet can be extracted
+  * from the TOC sequence of the first stream, which is located at the
+  * beginning of the packet, just like an elementary Opus stream:
+  *
+  * @code
+  * int nb_samples;
+  * int nb_frames;
+  * nb_frames = opus_packet_get_nb_frames(data, len);
+  * if (nb_frames < 1)
+  *   return nb_frames;
+  * nb_samples = opus_packet_get_samples_per_frame(data, 48000) * nb_frames;
+  * @endcode
+  *
+  * The general encoding and decoding process proceeds exactly the same as in
+  * the normal @ref opus_encoder and @ref opus_decoder APIs.
+  * See their documentation for an overview of how to use the corresponding
+  * multistream functions.

+   coded into a framed OggSquish bitstream by the second layer (see
+   docs/framing.txt).  Decode is the reverse process; we sync/frame
+   the bitstream and extract individual packets, then decode the
+   packet back into PCM audio.
+
+   The extra framing/packetizing is used in streaming formats, such as
+   files.  Over the net (such as with UDP), the framing and
+   packetization aren't necessary as they're provided by the transport
+   and the streaming layer is not used */
