Disguise a voice by shifting its pitch

Works with any file size -- files over 5000MB may just take a little longer

What is this tool?

Disguises a voice by shifting its pitch, useful for anonymizing a recording before sharing it -- for example, a whistleblower-style interview, or protecting someone's identity in a recording. Runs entirely in your browser -- the audio never leaves your device.

How to use it

Upload your audio file, choose how much to shift the pitch (lower for a deeper voice, higher for a lighter one), and download the disguised result. The duration stays the same either way.

This is a real, effective way to make a voice hard to recognize casually, but it isn't forensic-grade anonymization -- speech patterns, cadence, and word choice can still potentially identify someone regardless of pitch. For genuinely high-stakes anonymity needs, treat this as one layer, not the only one.
