3D Bass Booster

3D audio enhancement for browser tab audio — volume boost, bass, EQ, reverb, and surround.

3D Bass Booster — Volume Booster, Bass Enhancer, Equalizer & 8D Surround for Chrome Quiet YouTube videos? Weak Spotify web playback? Muffled podcasts or Twitch streams? 3D Bass Booster makes browser tab audio louder, deeper, and more immersive — with a professional-style toolset in a clean side panel. Unlike simple “volume only” extensions, 3D Bass Booster combines volume boost, bass enhancement, a 10-band equalizer, reverb, stereo widening, and 8D / surround spatial effects in one extension. Everything runs locally in your browser using the Web Audio API. Your audio is never uploaded, recorded, or sold. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHY 3D BASS BOOSTER? ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • All-in-one tab audio enhancer — volume, bass, EQ, reverb, surround • Real-time processing — hear changes instantly while you watch or listen • Side panel UI — EQ and Effects without cluttering the webpage • Built-in presets — quick styles for music, voice, movies, and more • Privacy-first — on-device processing; no account required for basic use • Optional PRO — higher boost limits and advanced controls for power users ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ KEY FEATURES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ VOLUME BOOSTER Amplify tab audio beyond the browser’s normal 100% limit. Free users can boost up to approximately 300% amplitude; PRO unlocks up to approximately 1000% for very quiet sources. Start low and increase gradually to avoid distortion on already-loud content. BASS BOOSTER Add weight and punch to music, movies, and games. Multiple bass styles let you shape low end from subtle warmth to aggressive sub impact. 10-BAND EQUALIZER Fine-tune your sound with a full graphic EQ. Adjust lows, mids, and highs to match your headphones, speakers, or content type. Includes preset curves for fast setup. REVERB Add space and depth with built-in room, hall, plate, studio, and specialty presets. PRO unlocks custom reverb tuning (wet/dry, decay, damping, pre-delay, early reflections, and more). 8D AUDIO & SURROUND Experience rotating spatial effects, path-based movement, frequency-controlled surround, and spatial modes designed for headphone listening. Visualizers help you see what you hear. STEREO WIDEN Expand the stereo field for a wider, more open soundstage. MASTER & PRESETS Built-in effect presets give you one-click starting points. Combine volume, bass, EQ, and effects into a sound that fits your taste. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WORKS WITH YOUR FAVORITE SITES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Any website that plays audio in a Chrome tab 1. Install 3D Bass Booster from the Chrome Web Store. 2. Open a tab with audio — for example, a YouTube video. 3. Click the 3D Bass Booster toolbar icon ON THAT TAB once. This grants permission to capture tab audio. 4. Open the side panel (click the extension icon again or use Chrome’s side panel). 5. Turn on enhancement and adjust Volume, Bass, EQ, and Effects. 6. Save your favorite sound with presets (PRO for unlimited custom presets). Tip: If audio does not start, click the toolbar icon on the playing tab first, then open the side panel. A built-in hint explains this step. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ FREE VS PRO ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ FREE (always available) • Volume & bass boost up to ~300% amplitude • 10-band equalizer with presets • Built-in reverb space presets • Basic surround / 8D controls • Stereo widen (up to 50% on manual adjust) • Built-in effect presets PRO (one-time purchase via Stripe) • Volume & bass boost up to ~1000% amplitude • Custom reverb advanced controls • Advanced surround parameters (higher speed, depth, and intensity limits) • Full stereo widen range • Unlimited custom presets — save your exact settings Purchase PRO from the side panel (GO PRO).

A: Chrome requires a user gesture on the audio tab before tab capture can start. One click on the playing tab enables enhancement. Q: Does this work on every website? A: It works on tabs that play audio. Some DRM-protected players may limit capture; most common music and video sites work when you follow the toolbar-click step. Q: Is my audio sent to your servers? A: No. Processing is local. Only PRO license checks use a small JSON API. Q: I paid for PRO but it did not unlock. A: Keep the side panel open after payment, or use “Restore with email” and enter the email from your Stripe receipt. Q: Can I use PRO on another computer? A: Use email restore on the new browser profile. Each profile gets its own install ID. Q: Will extreme volume damage my hearing or speakers? A: High gain can be loud. Always listen at safe levels. We show warnings at high settings.
