Hi Mus,

Just how much sound do you want to record? I don't think you can store much sound on that size EEPROM. Have you look at the ISD family of sound recorders? That might be a good route to go. I am in the alarm business and specifically work with the Sonitrol system which stores sound from as many as 16 microphones and stores the sound a few seconds before an alarm and a few seconds after the alarm and then the actual alarm trigger is sent to their monitoring station where the operator can "listen-in" to live sound and also playback the recorded activity. They use special chips from Texas Instruments. The sound board sends the stored and live audio to the main or base unit over a RS485 bus then on to the monitoring staion over standard phone lines. Very impressive system.

Back to your idea, the ISD chips can record from a few seconds to several minutes. Simple uC interface too!

There have been a number of posts on the forum regarding ISD chips. Check for them thru the search feature.

Hope this helps you out.
