Is there any library in C# that change human voice timbre

I'm searching for library that change timbre of human voice. I want to make small changes like: change deep male voice to little bit higher (something like change bass to tenor).
I think that changing voice in wider range - changing male voice to woman voice is too complicated and there is no good tool to do that, Am I right?

Solution

  • SoundTouch is an open-source audio processing library for changing the Tempo, Pitch and Playback Rates of audio streams or audio files.

    I think that changing the Pitch is what you're looking for...
