n64: disable certain debug messages for now as they're causing crashing problems.
...
fix audio, hopefully. sounds fine on diddy kong racing.

dual gameboy: sound
2012-12-29 17:11:19 +00:00

sound: fudge up some parameters of BufferedAsync. the most noticeable difference is that PAL NES with clock throttle no longer sounds horrible
2012-12-23 20:26:43 +00:00

dcfilter: more correct algorithm. doesn't sound any different. speed unchanged.

rearrange the api of DCFilter a bit to make it less dumb. nothing of real importance

Add Blargg's "blip_buf" as an unmanaged dll. license is LGPL; if I like the way it works, I'll rewrite it with MIT code. Implement it as the new resampling output track for NES. Small (~3%)? speedup. Should sound better, especially when the emulator can't quite keep speed.

break some stuff. FDS can eject and insert disk sides now

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.

dcfilter: reject out of range filterwidth

DCFilter: allow variable filterwidth. 2600 tia: use a rather aggressive (~172hz cutoff) dc filter. this coefficient is reasonably close to actual hardware behavior.

DCFilter: add a "push" mode more suited to being placed between a resampler and a metaspu
...
Gambatte: change the order of output from "GB => resampler => metaspu => DCFilter" to "GB => resampler => DCFilter => metaspu".
This doesn't change anything under most circumstances, except when playing the emulator in slow motion (for instance, 50% throttle). There, the metaspu sometimes adds silence to the output, which isn't actually silence if it has a different DC offset than the audio it's being mixed with. Well, 50% throttle sound output will always suck anyway...
2012-09-29 22:38:47 +00:00
1e6a9415c1
add Sound.Utilities.DCFilter and use it in gambatte
...
haven't decided yet whether i like the idea; it's mostly about playing nice with other audio mixing (from other applications)
well, it's not bad anyway...

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

cleanup/simplify SpeexResampler

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
b0e3a332d8
abstract resampling functionality into IStereoResampler for testing purposes
...
add two example resamplers that implement this: LinearResampler and CubicResampler. both are very basic and sound like shit compared to libresample4j
ultimately, a single good resampler with a better license than libresample4j should be selected and used
2012-09-05 21:21:35 +00:00
0430ec91c8
add resampler based on libresample4j (LGPL)
...
hook that up to libsnes, so libsnes audio now goes through libresample4j and then metaspu
it sounds ok

Add sound output to sound card while dumping is occurring. Uses a proxy ISoundProvider (DualSound.cs) to guarantee emulation sound core and dumping routine are unaffected, while sending "best effort" sound to system output. Doesn't sound great, but simple and functional.

Add 3-band equalizer. Not hooked up to client for time being though. Maybe later I'll expand it to more bands and create presets. Just wanted to check it in for now.

Max volume is settable per sound source to enable mixing many sound sources without clipping. Potentially can be used to disable individual sound sources.
