Ok, catched it. I reimplemented the SBC analyzer and synthesizer in
Octave which is easier to play around with and found that my C
synthesizer was working fine - on wrong subband samples. The bitstream
unpacker had a bug which made it shift the incoming bits once to often.

So sbc-test from the CVS is now able to decode 4 and 8 subband mono SBC
files (there's something wrong with stereo, I'll look into that
shortly).

I also moved all my static const tables to a separate header file and
replaced my cos() calls with precomputed tables. The decoder is still
about 5 times slower than the reference one, though.
