I was hoping to create a real time voice changer to either run on my computer or from a raspberry pi I own. Basically, I would speak into the microphone and then the sound would be played back in real time with special effects. I've searched stack overflow for a bit and found out how to do a robot voice by editing sine waves but I don't know a library to edit sine waves with. I'm on a windows 64 bit machine. Thanks
EDIT: The question is, how would I go about editing sine waves from the microphone in realtime?
