 | **Format** | Specifies the audio data format to import the audio clip as. You may want to use optimzied and compressed formats or raw PCM data for the best quality. In most cases you want to use the Vorbis compressed format, in order to save on memory use. Possible options: <table><tbody><tr><th>Option</th><th>Description</th></tr><tr><td>**Raw**</td><td>This is raw uncompressed audio data stored in pulse-code modulation format.</td></tr><tr><td>**Vorbis**</td><td>The compressed audio data stored in the Vorbis format.</td></tr></tbody></table>|
 | **Compression Quality** | The audio data compression quality. Used only if target format is using compression. Value 0 means the smallest size, value 1 means the best quality. |
 | **Disable Streaming** | If checked, disables dynamic audio streaming. The whole clip will be loaded into the memory. Useful for small clips (eg. gunfire sounds) or if audio streaming provides too much lag when starting to play the clip. |
 | **Is 3D** | If checked, the clip be played as spatial (3D) audio or as normal audio. 3D audio is stored in Mono format. |
-| **Bit Depth** | The size of a single sample in bits. The clip will be converted to this bit depth on import. Possible options:  **8**, **16**, **24**, **32**. The default is 16. |

What is, even more, the editor may start without a window (headless mode) and perform some additional actions like clearing cooker cache or project cache.
 Of course, all those things can be made manually by using Flax Editor C# API and Editor Plugins (see [here](https://docs.flaxengine.com/api/FlaxEditor.GameCooker.html)).
