augustss 860ebb7a92 Make little endian and big endian version of all functions 
that deal with 16 bit samples.  Let the drivers decide which ones
to use.

mycroft 592b1dd587 But seriously... 1998-08-09 21:41:45 +00:00
mycroft a85ed63924 Oops; the previous was wrong on little-endian machines. 1998-08-09 21:35:03 +00:00
mycroft 8cbcfa0df2 Add mulaw_to_slinear16 and alaw_to_slinear16. 1998-08-09 19:22:15 +00:00
augustss 27f70da904 Add alaw/mulaw conversion to/from 8 bit signed linear. 1998-05-22 13:05:31 +00:00
augustss c392128002 Audio: 
* Make it possible to use software assisted encodings that expand the
  sample size.
* Use 16 bits per sample when emulating mulaw coding on the SB.
* Prepare for SB16 without CT1745 mixer.

augustss 658656bb99 Audio changes: 
- Change the way attach and open works to allow multiple audio
	  devices.
	- Split the mulaw.c file into two to avoid dragging in mulaw
	  convertsion when they are not needed.  Add 16 bit alaw/mulaw tables.
	- Change the way audio properties are gotten.
	- Recognize more versions os SoundBlaster.

augustss 1bd32f9cad Add Alaw encoding emulation. 1997-05-28 00:07:46 +00:00
augustss 72b5ba3901 Redo the way selecting the mode for SB cards is done completely. 
It is now table driven since there are so many different variations
of SB cards out there.
Also fix a bug that stopped SB2 and SBPro from working.

augustss 37be371415 Clean up emulation code, SB, and GUS drivers and add some more encoding 
emulation to SB.

augustss e63a553175 Change the interface between high and lowlevel audio drivers again: 
Set the encoding parameters slightly differently.
Remove the SW encoding/decodinf functions from this interface
and move them to the audio_parameter struct; this is both more efficient
and flexible.
