Reading frequencies?

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. :)

Hello,

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