Slow down songs for practice or create Nightcore and Slowed remixes without annoying chipmunk voice distortions.
In traditional playback, speeding up music raises its pitch into squeaky chipmunk voices, while slowing down deepens it into a low growl. Independent pitch and tempo controls let you change playback speed without altering the musical key, or change the key without altering speed.
Worked example: Slow down a fast guitar solo to 75% speed for music practice
Input
A fast guitar track at 100% normal tempo.
Expected result
A track playing at 0.75x speed with every note staying in the exact original musical pitch.
Musicians can practice along at a comfortable speed without their instrument sounding out of tune with the recording.
Before you use the result
- Choose 'Keep Original Pitch' if you only want to speed up or slow down the tempo.
- Adjust semitones in steps of +1 or -1 to match your singing vocal range.
- Play the exported file to confirm smooth timing.
If the result is not what you expected
The audio sounds choppy at very slow speeds.
Extreme speed reductions below 0.5x can stretch sound waves past their natural limits. For smooth listening, keep tempo adjustments between 0.7x and 1.5x.
