WebEQ: Audio Equalizer & Sound Booster

Adjust sound frequencies (EQ) and boost volume for any tab.

What is WebEQ? WebEQ makes everything you listen to in Chrome sound better. It adds a room‑like sense of space, a clean 10‑band equalizer, and a volume booster to any tab, music, videos, podcasts, and calls. Use the simple one‑tap Spatial Audio toggle, or switch to Advanced for precise control. Why install it? Instant upgrade: Make laptop speakers or earbuds sound bigger and clearer.

Toggle Advanced for full control. How it works (in plain English) WebEQ uses the Web Audio API to route the tab’s audio through a high‑quality processing chain. Spatial Audio: a virtual speaker stage (front/center/rear) combined with early reflections and a subtle reverb tail—designed to feel like speakers in a room while keeping voices focused. EQ: 10 peak filters tuned for musical results. Compressor: light “glue” to keep boosted audio under control. Quick start Click the extension icon to open WebEQ. Simple mode: Adjust Volume. Flip “Spatial Audio” ON for a bigger, more immersive sound. Advanced mode: Choose a preset or fine‑tune the 10‑band EQ. Try small adjustments first (±2–4 dB). Your settings are applied globally across tabs. On some sites, click once on the page to enable audio processing (browser autoplay rule). Permissions explained activeTab + host_permissions (“<all_urls>”): Needed to access media elements on pages so audio can be processed in the tab. scripting: Used to inject the content script that connects audio to the Web Audio graph when needed. storage: Saves your presets and settings locally (and the current settings for global application). Privacy No account. No tracking. No analytics. Audio is processed locally in your browser and never leaves your device. We store your presets and settings using Chrome’s local storage only. Limitations Browser policy: Some sites require a click/keypress before audio processing can start. You may see a small “Enable WebEQ” prompt—click once and you’re set. Cannot process chrome:// pages or the Chrome Web Store itself (browser restriction). Very old or highly locked‑down pages may need a manual refresh after installing. Troubleshooting “AudioContext was not allowed to start”: Click on the page or the “Enable WebEQ” prompt to activate audio (browser autoplay policy). No change in sound: Make sure the tab is playing audio and that Spatial Audio or EQ adjustments are enabled. Conflicts: Other audio extensions modifying the same tab may interfere, try disabling them.
