AudioRetoucher is an audio effect processor that changes the pitch and tempo of an audio composition. With AudioRetoucher the sound of an instrument or voice might be modified slightly, to make a vocalist or instrumentalist's job easier in dealing with difficult keys, and usually involves no more than a half-step (semitone) or possibly whole step (whole tone) change.
