I can get sustained playback at 500% (that's like ripping at 5 speed). Reverse playback works at up to -400% reliably, that's enough for most 'scratching' purposes, unless the DJs speed their records up 10x for a period of a few seconds :) > The only solution is to keep in memory 100-200k samples before and past the > actual playing position, but I think reading backwards from a CDROM drive sucks > a lot. Oh, actually I never read 'backwards' from a CD, or for that matter decode an mp3 backwards. The ringbuffer is about 300K so that's enough for about 2 seconds of music.
