10-band equalizer, volume boost up to 8×, bass boost, vocal clarity, reverb, stereo widening — all on YouTube, Spotify, SoundCloud, Facebook, Twitch, Netflix, and any other website with audio.
Audio Booster works on nearly any website with media playback. These dedicated pages cover the most searched use cases and how the extension improves each platform.
Increase dialogue clarity, tame quiet uploads, and add more punch to music videos, long-form content, and livestreams.
Give playlists more low-end energy, lift vocals, and shape tracks with EQ when the web player feels flat.
Improve consistency across independent uploads, DJ sets, remixes, and mixes with fast per-tab audio control.
Make speech clearer in short videos, reels, live streams, and shared clips where volume and mix quality vary wildly.
Amplify any web audio up to 8× beyond the browser's native limit. Soft, loud, or max — you control it.
Fine-tune every frequency from deep sub-bass to crisp highs. ±15 dB per band with real-time visual feedback.
Feel the low end. One-click deep bass enhancement that adds punch and warmth to music, videos, and podcasts.
Cut through the mix. Boost mid-range frequencies so voices in videos, podcasts and calls are crystal clear.
Expand the stereo image for a concert-hall feel. Headphones, speakers — everything sounds wider and more immersive.
Add natural room acoustics with a single toggle. Perfect for immersive movie watching and ambient music sessions.
Keep volume levels even and prevent clipping when boosting. Loud parts stay controlled, quiet parts come forward.
Automatic volume levelling across different websites and media. No more manual adjusting between tabs.
Watch your audio in real time with bars, waveform, or circular visualizer modes — right in the panel.
One tap to transform your listening experience. Or create and save your own custom presets.
Audio Booster requests only the minimum permissions required. Here's exactly what each one does — and what it doesn't do.
"storage"
Stores your EQ settings, boost levels, custom presets, and UI preferences locally in your browser so they're restored every session.
"activeTab"
Allows the extension to interact with the currently open tab to intercept and process its audio output through the Web Audio API.
"scripting"
Required to inject the audio processing pipeline into the page. Without this, the extension cannot connect to the Web Audio API context used by websites.
Click "Add to Chrome" and confirm. Zero configuration needed.
Navigate to YouTube, Spotify Web, Netflix, or any audio-playing site.
