Python binding of WebRTC Audio Processing.

## Requirements

+ swig

+ compile toolchain

+ python

## Build

There are two way to build the package.

1. using setup.py

    ```bash

    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

    ```bash

    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

```python

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()))

```
