Speed up or slow down audio from 0.25x to 4x while keeping voices and music near the original pitch.
Use 0.5 for half speed or 2 for double speed. Pitch is preserved.
Change playback tempo for podcasts, lectures, interviews, music practice, transcription, language learning, or creative effects. Enter any decimal speed from 0.25x to 4x or adjust the slider.
A 2x setting makes the result about half as long, while 0.5x makes it about twice as long. Tempo processing preserves pitch, so voices do not automatically become squeaky when sped up or deep when slowed down.
The tool creates a new audio file in the selected format. Preview the source before processing and use the full Audio Editor when you also need trimming, volume changes, or background music.
The tempo process is designed to keep voices and music near their original pitch. Use Audio Pitch Changer instead when you want to transpose the sound without changing its duration.
The supported range is 0.25x to 4x. A 2x result is about half as long, while a 0.5x result is about twice as long as the source.
Yes. Changing tempo creates a newly encoded file in the selected format. Repeated conversion between lossy formats may reduce quality, so start from the best available source.
