Altering the pitch of your recorded voice can make you sound like a chipmunk, a monster and can even change your gender. Pitch shift is one of Audacity's many built-in effects, and allows audio engineers to raise and lower the pitch of vocals and instruments. Audacity's pitch shift effect can be used to raise the pitch of a recorded male voice with the purpose of making the voice sound female.
Click the "File" menu, then "Open..." Browse through your computer's folders to find the vocal file -- or session file that includes the vocal file -- you want to pitch shift. Select the file or session, then click "Open."
Record a male voice if you do not already have one recorded. Press "Record" and speak into your computer's microphone to record.
Highlight the track you want to pitch shift by right-clicking beside the file, and dragging the mouse over the waveform. Click the "Effect" menu, then "Change Pitch..."
Adjust the pitch settings in the "Change Pitch" dialogue box. Alter the pitch of the track by key, semitones, frequency or percentage.
Experiment with the degree of pitch change until the male vocal part sounds like a female vocal part. Expect to raise the pitch by approximately one octave. Click "OK" when you have finished pitch shifting.
Export the pitch-shifted track or session by selecting "File," "Export..." Choose a file name and file format. Click "Save."
The "Change Pitch" effect can be used to create harmonies that sound like female vocals. To create harmonies, duplicate the male vocal track, and pitch-shift the new track by 5 or 7 semitones. Raise the pitch of a male vocal part by 12 semitones (one octave) to create a female-sounding vocal track that remains in tune with the original music.
