/*
This code implements amr-nb audio encoder/decoder through external reference
code from www.3gpp.org. The licence of the code from 3gpp is unclear so you
have to download the code separately. Two versions exists: One fixed-point
and one with floats. For some reason the float-encoder is significant faster
atleast on a P4 1.5GHz (0.9s instead of 9.9s on a 30s audio clip at MR102).
The fixed-point (TS26.073) can be downloaded from:
http://www.3gpp.org/ftp/Specs/latest/Rel-5/26_series/26073-510.zip
Extract the soure into ffmpeg/libavcodec/amr
To use the float version run "./configure" with "--enable-amr-nb-fixed"
The float version (default) can be downloaded from:
http://www.3gpp.org/ftp/Specs/latest/Rel-5/26_series/26104-510.zip
Extract the soure into ffmpeg/libavcodec/amr_float
The specification for amr-nb can be found in TS 26.071
(http://www.3gpp.org/ftp/Specs/html-info/26071.htm) and some other
info at http://www.3gpp.org/ftp/Specs/html-info/26-series.htm
In the future support for AMR-WB might also be included here.
Reference code exist in TS26.173 and TS 26.204.
