+Real time streaming audio denoising using a [Dual-Signal Transformation LSTM Network for Real-Time Noise Suppression](https://arxiv.org/abs/2005.07551).
+
+Trivial to build as it uses the native rust Candle crate for inference. Easy to integrate into any Rodio pipeline.
+
+```rust
+    # 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>>
+```
