FAQ
The extension intercepts the audio stream from Apple and 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, FireFox, Brave and Microsoft Edge.
Only on Firefox for Android. Unfortunately Chrome and Edge extensions are not supported on mobile browsers.
No. The tuning only applies during your session on the YouTube video while the extension is active. It doesn’t alter the original file or your account.
Absolutely. It runs entirely in your browser and doesn’t interact with your Google account, YouTube login, or saved playlists.
We do everything to comply with Google, Microsoft & Mozilla’s policies so that the extension is compliant and will not be removed from the stores.
In an unlikely event where either of them will decide to remove our extension from its store we will provide the source code to all of our lifetime subscription users so that they can load it directly to their browser without having to install it from the add-on stores.
