G.729А for python 3

Encodes PCM 16-bit 80 sample chunks to 10 bytes of G.729А and back.

Good for speech.

Fixed compression ratio 16:1 (16kbps PCM -> 1kbps G.729A).

Usage

  • Linux x64, Windows x64

    you can use precompiled libg729a.so (linux) or libg729a.dll (windows)

  • Other

    cd src
make
cp libg729a.so ../python

See python/example.py for usage from python.

In the end you only need two files:

  • libg729a.so (linux) or libg729a.dll (windows) - g729a library file
  • g729a.py - python wrapper
