    Is the data contained in the audio file EXACTLY compatible with what the MCU needs to produce the sound?

    Pretty much what I thought -- you are operating clueless and asking poorly defined questions that may or may not have any chance of achieving your poorly understood and/or described objectives.

    First you need a system that can play audio. Something that has digital to analogue conversion.
    The file would be PCM (wav) and you can usually just rename a wav file as .bin, that's how the old Simmons SDS-1 does it, then burn it to ROM. It's basically an Eprom and a DAC, but it sounds like you've got a lot to learn before you do anything like this. I would need to learn a lot myself before attempting anything like this.

    Have a look here

    And, in this particular OP's case, therein lies the problem.
