AudioRetoucher 3.6.0.13

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. 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.
In additional, AudioRetoucher may work as Bass and Treble booster.
