Recurrent neural network for audio noise reduction, slightly improved for general use
RNNoise is a noise suppression library based on a recurrent neural network. RNNoise-nu is a modified version of RNNoise aimed to be a bit more general purpose.
To compile, just type: % autoreconf -i % ./configure % make
Optionally: % make install
While it is meant to be used as a library, a simple command-line tool is provided as an example. It operates on RAW 16-bit (machine endian) mono PCM files sampled at 48 kHz. It can be used as:
./examples/rnnoise_demo
The output is also a 16-bit raw PCM file.
