RNNoise is a noise suppression library based on a recurrent neural network.

## Original

To compile, just type:
% ./autogen.sh
% ./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 < input.raw > output.raw

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

## Extension

Compile with cmake:
% mkdir build; cd build; cmake ..; make

Extended rnnoise demo operation on int16/float32 mono wav file sampled at 48kHz
and output is wav file with the sample format as input file, vad also can be
output if vad file is supplied.

./bin/rnnoise_demo input.wav output.wav [<vad_prop>]
