Toggle it on/off from the toolbar to tame boomy bass instantly. Description LowCut gives you quick control over your tab’s low end. Flip the toolbar button to run a 330 Hz low-cut filter across every <audio> and <video> element on the page, or switch it off to hear the original mix. It uses a single high-pass biquad filter per media element—lightweight, transparent, and easy on system resources. What it does Toolbar toggle: One click enables the filter, one click restores the unprocessed audio. Automatic coverage: Newly added media is detected via MutationObserver, so the filter stays applied even on dynamic pages. Fallback support: If Web Audio can’t hook into a media element (e.g. CORS-restricted streams), LowCut requests tab capture as a backup route. Why you’ll like it Clean listening: Dial down muddy or rumbly bass instantly—great for podcasts, lectures, or background playlists. Zero setup: No sliders or advanced UI to learn; the toolbar title clearly shows LowCut: ON/OFF. Open source: MIT-licensed code, with icons under CC‑BY‑4.0. Source available on request at bubuit.net. Key Features High-pass filter at 330 Hz using Web Audio. State sync across tabs via lightweight messaging in extension/background.js. Automatic reconnection for new media in extension/content/content.js. Optional tab-capture fallback to maintain effect even when direct node attachment fails. How to Use Install the add-on and look for the LowCut icon in your toolbar. Click once to enable the low-cut filter on the current tab’s audio. The title updates to LowCut: ON. Click again to disable and return to the original sound. Works automatically on any site that allows Web Audio processing. Permissions Tabs & activeTab: Needed to send enable/disable messages to pages. Storage: Persists your ON/OFF preference between sessions.
