rust-onnx-example

Rust example using wavekat-vad

Uses wavekat-vad, a Rust library that provides a unified interface for multiple VAD backends including FireRedVAD. The FireRedVAD ONNX model and CMVN stats are downloaded and embedded in the binary at compile time — no manual model setup needed.

Features

• Pure Rust Mel filterbank + CMVN preprocessing (no C dependencies for audio features)
• Automatic resampling from any sample rate to 16kHz
• FrameAdapter handles frame buffering (feed any chunk size, get correctly sized 10ms frames)
• Works with any WAV file format (mono/stereo, any sample rate)

Usage

cargo run -- /path/to/audio.wav

Sample output:

File: audio.wav (16000Hz, 1ch, 16bit)
Duration: 3.50s (56000 samples at 16000Hz)

FireRedVAD — frame: 160 samples (10ms)
