Crate fast_vad 

Fast voice activity detection for 8 kHz and 16 kHz mono audio.

This crate provides three main entry points:

• VAD for batch detection over a full buffer.
• VadStateful for streaming detection one frame at a time.
• FilterBank for direct access to the underlying 8-band log-energy features.

The detector operates on fixed 32 ms frames:

• 512 samples at 16 kHz
• 256 samples at 8 kHz

Example

use fast_vad::{VAD, VADModes};

let audio = vec![0.0f32; 16_000];
let vad = VAD::with_mode(16_000, VADModes::Normal)?;
let sample_labels = vad.detect(&audio);
assert_eq!(sample_labels.len(), audio.len());
