Tue, 12 Aug 2008 00:24:42 +0000 Aaron Wishnick General 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 +0000 Aaron Wishnick Made 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 +0000 Aaron Wishnick The 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 +0000 Aaron Wishnick Cleaned up some bugs, but the FIR filter is still distorting. gsoc2008_audio_resampling
Sun, 22 Jun 2008 00:36:35 +0000 Aaron Wishnick Fixed 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
Thu, 19 Jun 2008 20:11:06 +0000 Aaron Wishnick IIR filtering now seems to work fine. Fixed point code also seems to be good. gsoc2008_audio_resampling
Wed, 18 Jun 2008 22:42:27 +0000 Aaron Wishnick Implemented a lot of fixed point code for the filters. The SDL_FixMpy functions currently don't work properly -- there are some issues with signed vs unsigned. gsoc2008_audio_resampling
Wed, 18 Jun 2008 18:55:50 +0000 Aaron Wishnick Began implementing IIR and FIR filters, and got zero stuffing and sample discarding working. gsoc2008_audio_resampling
Wed, 18 Jun 2008 04:51:10 +0000 Aaron Wishnick Added beginnings of resampling code. gsoc2008_audio_resampling
