goyuken	b40897bb77	sound api changes. added a new ISyncSoundProvider, which works similarly to ISoundProvider except the source (not the sink) determines the number of samples to process. Added facilities to metaspu, dcfilter, speexresampler to work with ISyncSoundProvider. Add ISyncSoundProvider to IEmulator. All IEmulators must provide sync sound, but they need not provide async sound. When async is needed and an IEmulator doesn't provide it, the frontend will wrap it in a vecna metaspu. SNES, GB changed to provide sync sound only. All other emulator cores mostly unchanged; they just provide stub fakesync alongside async, for now. For the moment, the only use of the sync sound is for realtime audio throttling, where it works and sounds quite nice. In the future, sync sound will be supported for AV dumping as well.	2012-10-11 00:44:59 +00:00
goyuken	f18eb2fef2	gambatte now has sound! output from the core is original 2MEGAHURTZ audio, but libspeexdsp handles it fine. ... seems to be a lot of DC offset at times; not sure if there's a good way to remove it	2012-09-09 00:41:11 +00:00

goyuken	001b28c60e	replace junk and bad license resamplers with libspeexdsp (using p/invoke). MIT licensed, sounds pretty decent. ... the p/invoke wrapper class is a hackjob i was using for testing and will be replaced.	2012-09-07 18:49:18 +00:00
