/* If you are using high playback or recording speeds, the default buffersize
is too small. DSP_BUFFSIZE must be 64k or less.
A rule of thumb is 64k for PAS16, 32k for PAS+, 16k for SB Pro and
4k for SB.
If you change the DSP_BUFFSIZE, don't modify this file.
Use the make config command instead. Seems to allow only 4K, 16K,
32K, 64K.
