About this extension
Tune Shifter - Your Audio, Your Rules.
Take complete control of any audio or video on the web. Whether you're learning that guitar solo at half speed, adding cavernous reverb to your lo-fi playlist, or power-watching lectures at 1.5x, Tune Shifter puts a professional mixing console in your browser toolbar.
🎛️ Studio-Grade Controls: Playback speed (0.5x–2x), real-time convolution reverb, volume boost, and pitch preservation, all in one slick brutalist interface.
🧠 Smart & Site-Specific: Settings persist per domain. YouTube slows down, Spotify stays normal. Your preferences, intelligently applied.
🔇 Zero Audio Hijacking: Reverb stays OFF until you enable it. No surprises, no broken sites.
One click. Total control. Tune Shifter.
