Over the last few months, i've been trying to speed up the ISO MP3 decoder, and also make it work on fixed-point maths. I thought I'd acheived my aim today when it decoded a file quick enough on my 3ghz pc that (in theory) it should play in real time on a 50mhz 486 i've got lying around. Then i tested the accuracy and.... although it sounds alright, its no where near good enough.
So I plan on rewriting the whole thing (copying bits accross but generally making it neater and also trying to get better accuracy at the same speed), but tbh this doesn't appeal as an individual project as its going to be a lot of work...
So does anyone want to help?
