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. Vocal pitch may also be speeded up to "smooth out" a performance, or to make the singer sound younger.
It may be used for special effects like famous Chipmunks recordings were created by recording vocal tracks at a slow speed, then boosting them to normal at playback. If you have MP3+G karaoke audio then all changes in Tempo will be synchronized with lyrics.
In additional, AudioRetoucher may work as bass booster, treble enhancer and BPM analyzer.
