Air Vocal Tuner Question

Hi Everybody i have a question about the air vocal tuner...what is the difference between the various detections? Peakes, selective, default, etc...thank you for your help

I don't actually know in detail. I checked the manual, but it wasn't terribly informative.

I do know that it has to do with how the algorithm decides what note you're trying to sing, and I believe that it affects which part of your vocal wave it takes as authoritative, but without more detailed documentation I really just don't know.
