[sci.electronics] Digitized sound playback

gub@ftp.COM (Glen Daniels) (02/08/90)

	Hi!

	Does anyone out there know of any single-chip digitized sound
generation systems?  Perhaps a chip (or chip set) that contains
memory, counters, and a D/A converter such that you can just amplify
the output, pulse a control pin, and it'll play whatever sound it's
got stored?  Or should I just go and design the gating logic and hook
it up to off-the-shelf memory and a D/A converter?

	Wondering,

Don't build this from scratch!!  I started to and then I met the CODEC.  CODEC's
are designed just to COde and DECode audio to digital (for ISDN).  If you want a
chip with memory also, keep looking.  I saw a complete module in an IC Masters
catalog - said it was for toys, etc. which needed audio record and playback.

Audio record/playback is a handy thing to have around.  I can't wait to get my
modules up.

Good luck.
