    Hi, is there a way that I could take, say, an mp3 file and read the audio frequencies with my oscilloscope? I guess it would be similar to the way a tuner tells you what note has been played?

    Hello,

    Music is a complex mix of frequencies, witch even change very fast.
    Next to the frequency change the volume will also change.
    It is very hard to get a good reading of music on a scope.

    There's a great little program called Goldwave that has an FFT real time spectrum analyzer. It's actually quite accurate. Best thing is, Goldwave is free. :)

    I think Audacity has that function too.

    Hello,

    Yes, Eric. Audacity has also an "show spectrum" FFT function.
    I use the linux version.
