Speed / Pitch

Change playback speed (keeps pitch) and optionally shift pitch in semitones.

Speed (0.5×–2.0×)

Speed uses atempo, which preserves pitch.

Pitch (semitones)

Pitch shift uses asetrate + aresample. Combine with speed as needed.

About

This tool lets you speed up or slow down audio for practical listening workflows. It’s great for podcasts and lectures when you want faster playback, or for language learning when you need slower, clearer speech.

Depending on settings, the tool can keep pitch while changing speed, and optionally shift pitch in semitones. This is also useful for musicians practicing along with recordings or matching a reference key.

For best results, adjust speed in small increments and export a short test clip first. After changing speed, you may want to normalize loudness to keep volume consistent.

FAQ

›Can I speed up without changing pitch?
Yes, use the mode that keeps pitch while changing tempo (time-stretch).
›Why does audio sound robotic?
Extreme time-stretch or poor source quality can create artifacts. Try smaller changes.
›What does semitone shift mean?
A semitone is the smallest step in common Western scales. Shifting changes perceived pitch up/down.
›Does changing speed affect duration?
Yes. Faster speed shortens the file; slower speed lengthens it.
›Will it work for speech and music?
Yes, but artifacts are more noticeable on complex music. Test and adjust settings.
