WebRTC Audio Processing for Python

Build Status Pypi

Python binding of WebRTC Audio Processing.

Requirements

  • swig
  • compile toolchain
  • python

Build

There are two way to build the package.

  1. using setup.py

    git clone https://github.com/xiongyihui/python-webrtc-audio-processing.git
    cd python-webrtc-audio-processing
    git submodule init && git submodule update
    python setup.py build
    sudo python setup.py install
  2. using Makefile

    git clone https://github.com/xiongyihui/python-webrtc-audio-processing.git
    cd python-webrtc-audio-processing
    git submodule init && git submodule update
    cd webrtc-audio-processing
    ./autogen.sh
    ./configure --with-pic
    make
    cd ../src
    make

Usage

from webrtc_audio_processing import AudioProcessingModule as AP

ap = AP(enable_vad=True, enable_ns=True)
ap.set_stream_format(16000, 1)      # set sample rate and channels
ap.set_ns_level(1)                  # NS level from 0 to 3
ap.set_vad_level(1)                 # VAD level from 0 to 3

audio_10ms = '\0' * 160 * 2         # 10ms, 16000 sample rate, 16 bits, 1 channel

# only support processing 10ms audio data each time
audio_out = ap.process_stream(audio_10ms)
print('voice: {}'.format(ap.has_voice()))
