Name: Recurrent neural network for audio noise reduction
Short Name: rnnoise
URL: https://github.com/xiph/rnnoise
Version: 91ef401
Date: Oct 10, 2017
Revision:
License: BSD 3-Clause
License File: COPYING
Security Critical: no
License Android Compatible:
Description:
RNNoise is a noise suppression library based on a recurrent neural network.
The library is used for speech processing in WebRTC.
Local Modifications:
* Only retaining COPYING and from src/ the following files:
- kiss_fft.c, kiss_fft.h
- rnn.c
- rnn_data.c
- tansig_table.h
* KissFFT: non-floating point parts removed, code clean, from C to C++,
class wrapper added
* BUILD targets and KissFFT unit tests added
* rnn_vad_weights.h: output layer sizes + weights scaling factor
* removing unwanted extern from constants in rnn_vad_weights.h and using
constants to declare array sizes
* Add braces around arrays in unit test.
* KissFFT removed
