David Kleingeld 0343b5ff06 Add new crate denoise required by audio (#38217)
The audio crate will use the denoise crate to remove background noises
from microphone input.

We intent to contribute this to rodio. Before that can happen a PR needs
to land in candle. Until then this lives here.

Uses a candle fork which removes the dependency on `protoc` and has the PR's mentioned above already applied.

1.1 KiB

Real time streaming audio denoising using a Dual-Signal Transformation LSTM Network for Real-Time Noise Suppression.

Trivial to build as it uses the native rust Candle crate for inference. Easy to integrate into any Rodio pipeline.

    # use rodio::{nz, source::UniformSourceIterator, wav_to_file};
    let file = std::fs::File::open("clips_airconditioning.wav")?;
    let decoder = rodio::Decoder::try_from(file)?;
    let resampled = UniformSourceIterator::new(decoder, nz!(1), nz!(16_000));

    let mut denoised = denoise::Denoiser::try_new(resampled)?;
    wav_to_file(&mut denoised, "denoised.wav")?;
    Result::Ok<(), Box<dyn std::error::Error>>
