Streamer in SDL_RunAudio should be totally implemented, but hasn't been tested yet.

Wed, 13 Aug 2008 02:50:10 +0000Implemented streamer code in SDL_RunAudio() but have not tested it. gsoc2008_audio_resampling
Aaron Wishnick <schnarf@gmail.com> [Wed, 13 Aug 2008 02:50:10 +0000] rev 2666
Implemented streamer code in SDL_RunAudio() but have not tested it.

Tue, 12 Aug 2008 01:03:05 +0000More streamer work. gsoc2008_audio_resampling
Aaron Wishnick <schnarf@gmail.com> [Tue, 12 Aug 2008 01:03:05 +0000] rev 2665
More streamer work.

Tue, 12 Aug 2008 00:50:58 +0000Added streamer code. I haven't yet incorporated it into SDL_RunAudio() though. gsoc2008_audio_resampling
Aaron Wishnick <schnarf@gmail.com> [Tue, 12 Aug 2008 00:50:58 +0000] rev 2664
Added streamer code. I haven't yet incorporated it into SDL_RunAudio() though.

Tue, 12 Aug 2008 00:24:42 +0000General cleanup and fixed a buffer overrun bug. It may be necessary to normalize filter gain differently or something. gsoc2008_audio_resampling

Thu, 10 Jul 2008 07:02:18 +0000Made a very significant optimization to the FIR filter which I believe I can take a little further. Right now the FIR filter size is 768 and I get some free() bugs, so this is something I need to debug. gsoc2008_audio_resampling

Wed, 02 Jul 2008 08:04:50 +0000The windowed sinc filter generation code seems to be working fine. The FIR filtering code is also now working reasonably well. Occasionally the FIR filter will pop, but setting the normalization factor lower seems to help this. I suspect the problem is in the fixed point multiply/add. I also have a hunch the zero stuffing/sample discarding code is not correct, and I'll look at that soon to get it sorted out. gsoc2008_audio_resampling

Wed, 02 Jul 2008 07:25:02 +0000Cleaned up some bugs, but the FIR filter is still distorting. gsoc2008_audio_resampling

Cleaned up some bugs, but the FIR filter is still distorting.

Sun, 22 Jun 2008 00:36:35 +0000Fixed lots of bugs in FIR filtering. Fixed point code is closer to working, but there seems to be overflow in the FIR filter resulting in distortion. gsoc2008_audio_resampling
