Pitch Tempo vs Amazing Slow Downer

Put the change into a downloadable recording

Pitch Tempo is built around a straightforward result: a complete audio file with the pitch and tempo settings you chose. Slow down for rehearsal, raise or lower the key, or combine the two changes before exporting. No desktop or mobile license purchase is required.

Amazing Slow Downer sells versions for desktop, iOS and Android. Its published prices and separate platform licenses make cost a concrete difference when comparing these tools for a short pitch-or-tempo edit.

Start on the device in front of you

Open Pitch Tempo in a supported browser and choose an audio file from your device. Set tempo from 50% to 150%, independently of a pitch shift from −12 to +12 semitones. Listen to the preview, then download the full processed recording in a supported format.

The website needs an internet connection and uploads audio for processing. A downloaded file stays on your device and can be used in your normal player. This workflow is for preparing a practice copy; there is no in-app phrase looping or automatic practice-speed progression.

Sound quality comes first

Our focus is clear, natural-sounding audio after a pitch or tempo change. Preview the opening of your recording before export, then download the complete result. WAV and FLAC preserve the processed audio without another lossy encoding step; MP3 offers a compact listening copy.

Keep a copy of the original and choose the smallest change that achieves your musical goal. The source recording and the amount of change affect the final sound.
