Hi la{d,u}-folk,
New sfront release (0.76) [see change log & pickup info
below], the main item of interest to LAD folk is that
the audio driver API in sfront has been enhanced -- its
now relatively straightforward to use sfront with
low-level audio API's that use a callback approach.
See the active driver section of the sfront reference
manual chapter on audio drivers:
http://www.cs.berkeley.edu/~lazzaro/sa/sfman/devel/adriver/index.html#active
for details. I would think this API should be sufficient
for a LAAGA driver ...
To test out the active driver API, I added PortAudio-based
support for Windows to sfront (via both WMME and DSound,
see www.portaudio.com for more details on PortAudio). This
went pretty smoothly, I was able to do a complete test of
PortAudio integration w/o ever touching a Windows machine,
by using the PortAudio Linux driver as a stand-in during
testing ... and reports from users doing alpha-testing on
various Windows platforms were positive.
