This guy http://www.barrymichels.com/ide/ is able to get 420kbs to/from static ram. I know they are good for much higher speeds. Of course, I don't have a good grasp on the overhaed of accessing them, so it could be that they won't be fast enough, but I'd be surprised... You should be able to buy 4MB flash chips from digikey. -Adam Nicholas Irias wrote: >I looked at compact flash first, but decided I couldnt simultaneously read >from more than one stream at a time at high rate, unless I have some sort of >RAM caching scheme. > >I'm trying to make a sound effects widget that can be programed with a wide >array of sounds (16 bit @ 22K sample rate) and then play back one or more >at a time, mixing as required.
