    help on audio files

    hi guys,
    does anyone of you know if it is possible to tag mp3 file(at various points in the file data), so that I can make a jump to any point in the audio file. I should write the program in C.

    I have an audio input, mp3 encoder/decoder.
    (for e.g., Say I should jump 10 min of play time, on every next click.)

    can anyone give me some idea?

    mp3 info is stored in frames, like any mpeg data file. you'll need to read documentation on these headers and do lots of bitwise operations. And note, a mp3 frame is 28 msecs long.
