I have 3 wav files:

  1. The original recording of a viola note
  2. A noisy re-recording of the original clip
  3. A different noisy re-recording of the original clip

I'm looking for a way to show which of the two noisy re-recordings is better than the other, and/or more similar to the original.

I can plot the time-domain waveforms and spectrograms which show that the signals are vaguely similar, but ideally I could find a measurement that gives me a single number - something like "recording 1 = 35% quality, recording 2 = 63% quality". I've tried "corcoeff".

In the image below, the original is in blue, the decent recording is in green, and the bad one is in red. enter image description here
