Ah. That helped. From that file, the 0x0022 wFormatTag is
WAVE_FORMAT_DSPGROUP_TRUESPEECH. Also, the 0x20,0x00 is the
size of the remaining raw header data I listed -- data that
is specific to the TRUESPEECH format. The 0x01,0x00 is the
revision and the 0xf0,0x00 is the number of samples per block.
The rest of the info, esp including the format of the data and all
details of the compression are, according to that document, not
available.
Bummer.
Thanks for the pointer. I'd managed to forget about wotsit. *How* I
don't know. But I had. :(
