Question about audacity

How do you narrow the waves down to view just the lower frequencies? Say like 20 to 80 hz? I'm having trouble finding what the notes are on some songs.

Why not just low-pass the song @ 80hz / high-pass @ 20hz, and then go from there?

I don't want to get into changing the song. I just want to view a certain frequency range to see where the peaks are.

Analyze -> Plot Spectrum

Exactly. High-pass it and low-pass it like I said, then use the Plot Spectrum tool. After you find the frequency, all you have to do is exit out of Audacity without saving over the song (or just undo twice)

There is still a better way to do it than that, I just forgot how to do it. You can view a graph of DB of certain frequencies.

Did you try switching the Frequency Analysis Algorithm to Spectrum, Size to 4096 or higher, and Axis to Log frequency? Granted, you must select a small sample of music data prior to doing this.

If that is not enough for you, you could always export your results to a text file and rebuild your graph in a spreadsheet.
