👋 Hey Product Hunt! I'm the solo developer behind Audio Booster — and I'm really excited (and a little nervous) to finally share it here. Why I built it: I kept running into the same frustration — a YouTube video too quiet to hear, a movie where the dialogue was buried under the music, and that flat, "stuck-in-your-head" feeling when listening on headphones. Browsers give you one volume slider and nothing else. I wanted a real audio engine living right in the tab. What it does: 🔊 Real surround — upmix any tab's stereo to 2.1, 4.0, 4.1, 5.1, 7.1 or 7.2 🌀 8D spatial sound (HRTF) — true binaural audio that orbits around your head 📈 Volume booster up to 200% for those too-quiet videos 🎚️ 7-band EQ, 🗣️ dialogue boost, 🌙 night mode, crossfeed, limiter/normalizer 📌 Per-site memory, custom presets, a live analyzer (spectrum, 3D sound field, LUFS) and 24 languages A few things I care about: 🔒 Privacy first — your audio is processed 100% locally and never leaves the browser. 💛 Completely free — no ads, no paywalls, no locked features. Built and maintained by one person. If it's useful to you, a donation helps keep it alive, but it unlocks nothing — everything is already free. It works on Chrome and Edge, on any site (YouTube, Netflix, Twitch, Spotify web, games…). I'd genuinely love your feedback — what audio systems do you use, and what should I build next? I'm reading every comment today. 🙏 Thanks for checking it out!
