ITU G.729 Annex A compatible audio codec

 Bcg729 is an open source implementation of the ITU G729 Annex A
 speech codec. Written in C 99, the library is fully portable. It
 runs on many platforms, including ARM and x86.
 .
 Bcg729 supports concurrent channels encoding/decoding for multi
 call application such as conferencing.
 .
 The project was developed as part of mediastreamer2, Linphone's
 media processing engine. It therefore also contains the glue for
 integration into Linphone/mediastreamer2.
