The YouTube Music Re-Tuner Browser Extension is a browser add-on that allows you to retune the audio of YouTube videos or music on YouTube Music in real time. Whether you prefer listening in 432 Hz instead of 440 Hz, or want to experiment with other pitch adjustments, this tool makes it seamless without downloading or converting the files manually.

The extension intercepts the audio stream from YouTube, applies a real-time pitch-shifting algorithm, and then plays it back to you—retuned to your desired frequency (e.g., 432 Hz). The video remains synchronized while audio playback is adjusted on-the-fly.

Currently, the extensions are compatible with Google Chrome, Brave and Microsoft Edge.
