PCM API enhancement - more bitmasks to support more formats

PCM API enhancement - more bitmasks to support more formats

[Jaroslav Kysela]

Hi,

	I've modified and clean up Takashi's patch to add support for more 
formats. It keeps binary compatibility (important for the kernel inclusion)
and adds some space for future expansion now. The code is in CVS.
	Does somebody have an URL to 24-bit WAV files? I'd like to add
support for this format to aplay/arecord. Thanks.

						Jaroslav

Hi Jaroslav,

you might be interested in next site:
http://www.tsp.ece.mcgill.ca/Docs/AudioFormats/WAVE/WAVE.html

it contains Microsoft's Riff Wave specs. Noticable the 'Multi-channel / high bit resolution formats ,
2001-06-18' might be interesting for you. It contains also some sample data in various formats

Enjoy,
Frank.
