So I have a program that works for a guitar, and sinewave and a saw tooth wave . so If a have person sing a note, it should work for that right ? I am not talking about sing a whole song but just a note. so like when people sing the scales: do ra me fa so la ti do is should would for that right ? are there something I do not know ? I do know the human voice is closest to a saw tooth wave. also would it work if a person sings a song acapella?
