Fundamental Pitch Conversions

Hello everyone,
I am a new user to audacity, and I’m really familiar with much of the audio editing functions it supports. I was wondering if anyone here knows how to create an effect that will transform a sound file (I plan to use a short speech .wav) into a series of only the Fundamental Pitches? I know Audacity can find these pitches, but I’m not familiar enough with the program to actually make it on my own. If anyone could help, it’d be much appreciated.

If you are wanting to extract specific “tones” from a more complex waveform, you can create a narrow band filter using the Equaliser effect. It will not give you “single” frequencies (as there are an infinite number of these and it can not pick out one from an infinite number), but it will give you quite a narrow band of frequencies.
