Key Features & Benefits: - Up to 600% Sound Boost — make quiet videos, podcasts, lectures, and music crystal clear and loud. - Full Spotify, Netflix & YouTube Support — powered by modern Tab Audio Capture technology, it works flawlessly on all websites, including DRM-protected platforms. - 1-Click Presets — quick buttons to instantly set volume levels (100%, 200%, 400%, 600%). - Smooth & Precise Control — intuitive slider to fine-tune audio for your headphones or speakers. - Per-Tab Memory — automatically remembers saved volume settings for each active tab. - Audio Tab Switcher — easily view and jump between tabs playing audio directly from the extension popup. - Lightweight & Fast — zero lag, minimal memory and CPU usage. Full screen Mode - unlike many other volume boosters, ours does NOT break YouTube's fullscreen mode or video controls. Enjoy loud audio in full screen with zero glitches or blue borders! NEW: Remove Vocals (Beta) Turn any tab into a karaoke track. Toggle vocal removal on top of your volume boost to reduce vocals on songs and videos where they're centered in the mix. This is a beta feature using audio phase-cancellation — it works great on many tracks, but it's not perfect AI separation: vocals with heavy reverb, doubled tracks, or non-centered mixing may only be partially reduced, and some centered bass/drums can be affected too. We're actively improving it! How to use: 1. Click the Volume Control extension icon in your Chrome toolbar. 2. Adjust the slider or pick a preset button. 3. Enjoy boosted, high-quality sound! Frequently Asked Questions (FAQ): Does it work in Incognito Mode? - Yes! Just enable "Allow in Incognito" in your Chrome extension settings. Is it safe for my speakers or headphones? - Yes! We recommend raising the volume gradually to find a comfortable listening level without sound distortion. Enjoying the Audio Booster extension? Support us with a review!
