Texas Instruments make a CVSD voice recorder chip, the number escapes me for
the time being. However it can be clocked perhaps a little vaster than the
ISD one. It can address up to 256K bits of RAM. Single bit. And uses an
ordinary DRAM chip. I'd messed with these before with just such an idea.
Though I'd never actually got anything serious off the ground. The problem
with these guys is that they only come in a shrink-dip. Which means they're
incredibly difficult to breadboard.

The clock on this chip is variable so the slower the clock the longer the
sample time. But that also means that the faster the clock, the better the
quality. My idea was to use it as a sampling drum machine. That was until I
got a sampling drum machine and made some music instead.

Perhaps check out the TI web site for a CVSD (Continuously Variable Slope
Delta modulated) voice recorder.

Hope this helps.
