Need help finding a Chip for sound recording device

Archived from groups: alt.comp.hardware.homebuilt (More info?)

Hi, first time user to newsgroups so bare with me please ^^.
I am studying in in Genie electronique, option Ordinated Systems and I am
looking for a Dual in line chip (around 28 pins) that can be used to record
30 seconds of sound , play it normally and has the function of playing it
backwards. I have found chips that can do way better but it will only be
used for a small project and I won't have time to work alot on that small
proect. It is a specialized chip exactly for that kind of application.
Can't find any info on it anywhere. If someone knows any information on a
chip that fits that description, I'd really appreciate it if you could share
that information. Thank you for your time.
