It would be interesting to see how this performs, compared to simpler methods, on hard cases like a missing fundamental. (If you play a sound with power at 200 Hz, 300 Hz, 400 Hz, ..., i.e. all the multiples of 100 Hz but not 100 Hz itself, humans always perceive a pitch of 100 Hz.)
- zeroxfe 7y agoI have training data which includes examples with missing fundamentals (synthetically removed), and the network does learn to recognize this. (The heavy regularization also helped a lot.) Although I was able to test with real instruments (and my grotesque voice), I didn't find any good live examples of audio with missing fundamentals to test with. It did recognize held-out synthesized data correctly though.
