nnnoiseless

nnnoiseless is a rust crate for suppressing audio noise. It is a (safe) rust port of the RNNoise C library, and is based on a recurrent neural network.

While nnnoiseless is meant to be used as a library, a simple command-line tool is provided as an example. It operates on RAW 16-bit little-endian mono PCM files sampled at 48 kHz. It can be used as:

cargo run --release --example rnnoise_demo INPUT.raw OUTPUT.raw

The output is also a 16-bit raw PCM file.
