Anybody who has an idea on how to play any digital recorded audio (.WAV / MIDI) from any device like flash drive or compact flash device? PIC Micro will read a particular addressed audio file for playback. The design is for a simple security system that instead of turning an alarm, PIC will pick an appropriate digital recorded audio and feed it to the amplifier.
 

If .wav file is stored in raw format, then you just have to keep on reading byte and sending to DAC + Audio Amp. to listen

hi pal, thanks for that. Could you pls share some tech. info regarding the interfacing of flash drives to microcontroller including the fundamental background on how to read .wav files in raw format.
 

You can use SD/MMC via SPI, I think it's easier than CF which is paralel with adressing.
See h**p://www.mikroe.com/en/tools/mmc/

Notice that you'll need level conversion with voltage divider if you aren't using 3V logic.
