I have two audio signals, both with supposedly matching frequencies at each time window. What I would like to do is to verify that the frequencies are identical. However, one was created at a higher power than the other, so simply checking for a match at each sample won't work. I've already cross-correlated the signals, so there's no time lag between them.
Is there any way to compare the "shapes" of two waveforms of differing amplitudes? If there's some way to drop the amplitude domain from the signal, that would work - I don't know nearly enough about DSP to know if it's easy or not.
