One hint: You might first check what alsa calls PCM - If memory serves me correctly, it is not LPCM.
It is already mu-Law or a-Law (depends on if the developers had a European or USA telephone network).
It that is so - then you should already have the compression / de-compression code in the alsa tree. |
You know I checked for ALaw and MuLaw support on the card level (which isn't there for the record unsurprisingly) The gory details are on the audio thread somewhere but in essence the card said
no to both
I never thought to see if the internalised implementation was of value. Good thought
That's an absolutely cracking tutorial by the way, mucho kudos
