Open Auto-Tune on any audio track in your audio editing program, such as Pro Tools, Ableton, Record, Logic or Audition.
Click the "Graph" mode button in the upper-right part of the program.
Click the "Track Pitch" button toward the bottom-left of the screen.
Play back your audio track for as much of the track as you want to edit. Playback can be initiated in most programs by pressing the space bar or by locating and clicking the "Play" symbol. It can be terminated by pressing the space bar a second time or by locating and clicking the "Stop" symbol.
Press "4" to select the "Pointer" tool. You can now drag up or down sections of audio. You can also grab the end of a section of audio and drag only half of the audio. Press "5" if you need to use the "Scissor" tool to break sections into smaller sections. This is useful for when two or more notes are in the same section.
Press "3" to select the "Draw" tool, a unique tool that allows you to cheat at changing pitch. To use this tool, simply click on a note line exactly where you want your audio to convert to that note. Drag the box for as long as you want the pitch to remain the same and then release the click.
Rotate the "Transpose" knob if you desire to change the pitch of the entire recording to a higher or lower key.
