Does anybody know how to load sound onto the ATtiny2313 ?

[rocket100]

Does anybody know how to convert sound files such as, midi, aif, or mp3 to C-code so I can burn that to the ATtiny2313 and have it play back the sound.
I heard that you can use PWM but I don't know how to do that.



thanks...

The tiny2313 only has 2kB of space for stuff, even mp3 format songs would only be able to play for a fraction of a second with that limited space, and that's not even considering you would need at least 1kB of program space for decoding the data.

I was thinking of just using low quality sound effects for my robots.
And if those small microcontrollers covered with black epoxy on circuit boards can store sounds for toys I don't see how the tiny2313 couldn't hold sounds.

The things under the epoxy aren't microcontrollers so you are comparing apples to oranges.

You can get external boards to play sounds, eg. http://www.futurlec.com/Mini_MP3.shtml

Or you could just buy a cheap MP3 player and hack it.
