Re: about voice

where i can find some doc about the internal, undocumented, calypso buffer format?

As pointed out, there is no documentation.

I don't remember exactly how I learned what the format was ... (probably trial and error, possibly a few hints from the DSP code ...)

I've just pushed support for the FR codec buffer format in gapk (thanks to steve-m for the sample file btw). http://git.osmocom.org/gitweb?p=gapk.git;a=commitdiff;h=cfaec3a2f6590bafcaec...

I'll do EFR and HR format whenever I get sample files (but I'm away from my hw right now).

Cheers,

Sylvain
