Audio Modulator — Volume, Pitch and Tempo Control
Even out inconsistent levels, shift pitch up or down, and change tempo — all processed in your browser. It covers the corrective work most recordings need before they are worth publishing.
Normalising volume is the fix most recordings need
Recordings made on different days, in different rooms, or by different people almost never match in level. The result is a listener reaching for the volume control, which is the most reliable way to lose them. Normalisation raises everything to a consistent target so a series of clips plays at one comfortable level.
Pitch and tempo are separate controls
On a tape deck they were the same thing: play faster and everything goes higher. Digitally they are independent, which is what makes pitch correction on sped-up audio possible. Shifting pitch alone is the tool for voice disguise or creative effect; shifting tempo alone tightens or stretches timing while the voice stays recognisable.
- Normalise volume — the fix for inconsistent recording levels
- Shift pitch without changing speed — voice effects and disguise
- Change tempo without changing pitch — tighten pacing naturally
How to use it
- Load your audio. Open the Audio Modulator and select your audio or video file.
- Apply your adjustments. Normalise the volume, shift the pitch, or change the tempo.
- Export. The processed audio renders locally and saves to your device.
Frequently asked questions
What does normalising volume actually do?
It raises the whole recording to a consistent target level, so clips recorded at different times play back at the same comfortable volume.
Can I change speed without the chipmunk effect?
Yes. Tempo and pitch are independent controls here, so you can change one without affecting the other.
Will normalising make background noise louder?
Yes — raising the level raises everything, noise included. Denoise first, then normalise.
