Crate sonora 

Sonora

Pure Rust implementation of WebRTC audio processing – the full pipeline with echo cancellation (AEC3), noise suppression, automatic gain control (AGC2), and high-pass filtering.

Provides a Rust API. A C API is available via the separate sonora-ffi crate.

Usage

use sonora::{AudioProcessing, Config, StreamConfig};
use sonora::config::{EchoCanceller, NoiseSuppression, GainController2};

let config = Config {
    echo_canceller: Some(EchoCanceller::default()),
    noise_suppression: Some(NoiseSuppression::default()),
    gain_controller2: Some(GainController2::default()),
    ..Default::default()
};

let mut apm = AudioProcessing::builder()
    .config(config)
    .capture_config(StreamConfig::new(48000, 1))
    .render_config(StreamConfig::new(48000, 1))
    .build();

// Process 10ms frames (48kHz * 10ms = 480 samples)
let src = vec![0.0f32; 480];
let mut dest = vec![0.0f32; 480];
apm.process_capture_f32(&[&src], &mut [&mut dest]).unwrap();
