Gain - Volume Booster par Hookset

Gain gives you real control over your browser audio.

If a video is too quiet, a stream is mixed badly, or Firefox just does not go loud enough, Gain lets you boost any tab from 0% to 600% using the Web Audio API, far beyond the browser’s built-in limit.

Key Features:

• Volume control from 0–600% on supported tabs
• Bass Boost and Voice Boost EQ filters
• Dark mode, synced across popup and settings
• Blacklist and whitelist for site control
• Audio tabs list to see tabs currently playing sound
• Per-site volume memory for faster repeat use
• Default volume setting for newly activated tabs
• URL-change reset to prevent boosted settings carrying into a new video or stream
• Click-to-use activation with optional per-site persistent access
• Playlist-friendly option to keep settings when the URL changes
• Intricate settings control, including behavior and interface customization
• Dynamics compressor to reduce distortion at higher gain
• Live toolbar badge, color-coded by volume level
• Direct number entry for precise volume control

Keyboard controls: arrow keys adjust volume by 1, Shift + Arrow Key adjusts in steps of 10.
