Sound Adjuster by tropic

Sound Adjuster provides additional audio controls for media playing in Firefox.

Features:
• Volume gain from 0× to 5×
• Left and right stereo balance
• Five-band equalizer with presets
• Mono and left/right channel controls
• Light and dark themes
• Automatic detection of newly loaded media

Your selected gain remains active when the popup is closed. Sound Adjuster can also apply the current settings to new media loaded on the same page, including dynamically updated feeds.

Compatibility:
Sound Adjuster works with standard HTML audio and video elements. Some websites use cross-origin media, DRM, or other browser security restrictions that prevent extensions from safely processing their audio. In these cases, Sound Adjuster leaves playback unchanged and displays an availability message.

Privacy:
Sound Adjuster operates locally in your browser. It does not collect, store, or transmit user data and does not include analytics or tracking.

Sound Adjuster is open-source:
