AudioRetoucher is an music transposition tool 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. AudioRetoucher mainly used by musicians as MP3 key shifter, but it also can detect BPM values for MP3 files and adjust tempo in real time.

Thank you to the developers of AudioRetoucher. I tried the trial version and immediately sent payment for the full version. It provides greater quality and easier use than other similar software and hardware I have reviewed. Great job. I am using this as a musician... to adjust pitch of recorded songs to proper or different keys (at original tempo) for matching my instruments' tuning (without retuning). I also use it to slow songs for learning difficult passages.
