Is the propeller fast enough to decode mp3 in realtime?
Has anybody already tried this?

    The SLOWEST system I've ever seen decode a MP3 in realtime was an ARM9 running at 40mhz.

    The likelyhood of being able to decode it in realtime is pretty low, since it's not a process that can be parallelized well. Especially without internal higher level math functions, a good external ram bus, etc.

    You might look into using a MP3 decoding co-processor, they are a dime a dozen now.

    Yes, a chip like the vs100x would be a good choice, but I was curious if someone had a clever
    idea of how to do it in software with such a limited hardware.

    I remember that an intel 486/33 was the absolute minimum to decode a 128kbps
    mp3 (running a DOS mp3 player).
