About

RNNoise is a noise suppression library from Xiph.Org based on a recurrent neural network. It runs locally as a C library and builds from source. The example tool reads raw 16-bit mono PCM at 48 kHz, so other audio must be converted first.

What you can do with it

Suppress background noise in recorded speech on your own machine
Embed real-time noise suppression in a C voice application
Denoise raw PCM audio from the command line demo tool

Get started

Build the library from source with autogen, configure and make
Convert audio to raw 16-bit mono PCM at 48 kHz

Example

./autogen.sh && ./configure && make
./examples/rnnoise_demo noisy.pcm denoised.pcm
