The audio/rnnoise port
rnnoise-0.0.0.20210312p0 – recurrent neural network for audio noise reduction
RNNoise is a noise suppression library based on a recurrent neural network.
A description of the algorithm is provided in the following paper:
J.-M. Valin, A Hybrid DSP/Deep Learning Approach to Real-Time Full-Band Speech
Enhancement, Proceedings of IEEE Multimedia Signal Processing (MMSP) Workshop,
While it is meant to be used as a library, the code for 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.
