Default Playback sound files controlled by a Pic

Hello All,

For my next project, I would like to develop a circuit using a PIC microcontroller (ex: 16F628a) that would control another part of the circuit that allow playback of pre-recorded sound files (wav or MP3).

Basically, I want to reproduce those child games were you press a button and you hear an animal sound for example. Actually, it would need to be able (if possible) to be able to play multiple sound at once by pressing multiple button...

I am really at the beginning of this project, and I am not sure where to start...

Do you know any chip/circuit that already have this capability?

Any help would be appreciated!

thank you,

Rickydou

google the diy mp3 player and you will see.

pic can be interfaced with sd/mmc card for the prerecorded sound file. then let the pic feed these data to the mp3 decoder chip/dac then you get the audio signal.

Yesterday i stumbled upon this article:

It features a development board for audio development on a PIC (with DSP) and has a nice set of audio peripherals. For less than 60$ that might be a nice place to start.
