[music-dsp] recursive SIMD?
Hi there. (Long time reader, first time poster. Yay!) I haven't done much with SIMD in the past, so my experience is pretty low, but my understanding is that each data piece must be defined prior to the operation, correct? Meaning that you can't use result of the operation of one piece of data as the source data for the next operation, right? This came up in thinking about how to optimize an anti-aliasing routine. If, for example, the process is oversampling by 4 and running each through a low pass filter and then averaging the results, I was wondering if there's some way of using some SIMD process to speed this up, specifically the part sending each sample through the filter. Since each piece has to go through sequentially, I would need to use the result of the first filter tick as the input for the second filter tick. But that's not possible, right?

Haha - see also: http://createdigitalmusic.com/2015/04/thx-deep-note-creator-remade-iconic-sound/ The original 30-year-old C program is 325 lines, and the “patch” file for the synthesizer was 298 more lines. I guess it just felt like 20,000 lines when I did it. I know the feeling ;-) On Apr 11, 2015, at 4:00 PM, robert bristow-johnson r...@audioimagination.com wrote: On 4/11/15 6:46 PM, Vicki Melchior wrote: It should appear in their listings and archives but I don't see anything very obvious on the NPR-ATC website for Apr 11 : http://www.npr.org/programs/all-things-considered/ What was it about? sorry, just now clicked your link, Vickie. it's this: http://www.npr.org/2015/04/11/399034279/know-that-thx-sound-before-movies-thats-actually-20-000-lines-of-code -- r b-j r...@audioimagination.com Imagination is more important than knowledge. -- dupswapdrop -- the music-dsp mailing list and website: subscription info, FAQ, source code archive, list archive, book reviews, dsp links http://music.columbia.edu/cmc/music-dsp http://music.columbia.edu/mailman/listinfo/music-dsp -- dupswapdrop -- the music-dsp mailing list and website: subscription info, FAQ, source code archive, list archive, book reviews, dsp links http://music.columbia.edu/cmc/music-dsp http://music.columbia.edu/mailman/listinfo/music-dsp

I know the feeling ;-) i was wondering about that (20,000 sounded awful large). i thought they might have meant *all* of the system and utility code that was called to do it. -- r b-j r...@audioimagination.com Imagination is more important than knowledge. -- dupswapdrop -- the music-dsp mailing list and website: subscription info, FAQ, source code archive, list archive, book reviews, dsp links http://music.columbia.edu/cmc/music-dsp http://music.columbia.edu/mailman/listinfo/music-dsp
