[dorkbotpdx-blabber] Microcontroller + RAM.. recording/playback

[Alex Norman]

I'm looking to build a very simple audio/control voltage recorder/"sampler" with
a micro-controller.  I realize a DSP might be the best thing for this but I'm
curious if I can do it with a micro-controller for cheap.  Basically, the piece
that is the major problem is finding a reasonably large memory device which I
can quickly read and write single bytes at a time.  Obviously this calls for
RAM.  I'm hoping that I can read bytes at at least 88.2khz and write at the same
rate, at the same time.  500KB would be ideal but as little as 64KB would be fun
to work with.

As usual I try to stick with DIP as much as I can, but maybe this won't be
possible..

Anyone have any recommendations or experience with this sort of thing?

I've been thinking that I could actually do this with eeprom if I make it so
that the device doesn't 'record' and 'playback' at the same time.. but it would
be ideal if I could do both..
