Audacity Forum

You can't bring down the pitch of just one voice if it is mixed in with the other voices.
You can bring down the pitch of all the sound by using the "Change Pitch" effect.

Imagine that you have some red paint, some blue paint and some yellow paint and you mix them all together in a big bucket. That is like the "mix" of three different voices. Now lets say that you want to heat up the red paint to make it hotter, without heating up the blue or the yellow paint - you can't do it. Once they are mixed together, what you do to one you do to all. Similarly once they are mixed together you can't take the red paint out of the bucket, and you can't extract that one voice from the mix of voices.

I guess that I'm looking for an application that will allow me to set a maximum frequency. Anything above that maximum would not be cut off, but just reduced to that maximum. This does not seem to be an impossible request to me. There must be a way to analyze frequencies, even if Audacity does not have that ability.

Or am I expecting too much of modern technology (LOL)?

Unless the person with the falsetto voice is singing on their own, or you have that person in their own track, there is nothing you can do.

If the person is solo, you can reduce the volume of frequencies above a certain level to the point where the frequencies above that level are no longer audible. That doesn't move down the pitch of frequencies that were previously above that level, just makes the same frequencies quieter. There is no time stretching involved, so it doesn't change the pitch of that person's voice.

Was it Effect > Change Pitch you were trying to use (you want to change the pitch without changing the tempo)? If the person is solo, it might achieve something of what you want, but you do have to apply it just to those sections you want to change (but not to each note).

I would think some professional (expensive) programs might have an envelope type of tool with a curve to adjust the pitch of parts of a recording - that still seems to me to be what you are asking for, not to affect the pitch of everyone singing at other points in time. I certainly know one program that does this with pure speed change, therefore affecting pitch and tempo.

I think that Melodyne can do what you are asking, but it is labour intensive, note by note process and the software cost around $300
