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

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.

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.
