Speex echo canceller on TI C55 DSP
...uggest here.
OK, I understand what you mean now. kiss_fft is a separate packaged I
merged into Speex, but which I haven't yet fully converted to use the
Speex functions/macros.

My builds for the two platforms used exactly the same source files, though
there were a few ifdefs in the test_echo routine to deal with file I/O for
the C55 with its 16-bit char size. When I get a chance, I will add some
instrumentation and see if I can find where things diverge. Just looking at
the canceled audio files with a waveform editor, they were not obviously
different, so it is not a burning issu...
