I am actually designing an embedded system.
I would like to add a system to register sounds through a mic recod them on SD and thenplay them.
I alreday have the MCU and SD card.
I just have to design the two schematics (capture and play).

It should be able to record and play human voice in a clear and audible way. no need to be to powerfull.

PLease don't hesitate if you have any clues!!

Charles
