[speex-dev] Raw Speex?

[Jean-Marc Valin]

What happens is that on most mode, there isn't an integer number of bytes for
each encoded frame, so you either need to do like sampleenc/sampledec or you can
 use the speex_bits_write_whole_bytes and speex_bits_read_whole_bytes functions
to get optimal packing.

> Or is it the amount of data you have to give to each call to 
> speex_bits_read_from()? Or both? Or neither?
