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 <number of channels> <maximum attenuation> [model to use] < input.raw > output.raw The output is also a 16-bit raw PCM file.
