Audio Console / Mixer by Sammiously

Audio Console turns Firefox's sidebar into a professional mixing desk for your browser tabs. Every tab playing audio gets its own channel strip. Control volume, panning, stereo width, and apply a full chain of studio-grade effects - all in real time.

Per-tab channel strips
Each active audio tab appears as a dedicated channel with a calibrated fader (−∞ to +12 dB), a pan knob, a stereo width control, and instant mute/solo. Strips can be renamed, reordered by dragging, and collapsed to a slim view. Tab group colors are shown right on the strip.

Professional metering
Stereo L/R peak meters with independent peak hold on every channel, plus inter-sample true-peak detection and integrated LUFS loudness (ITU-R BS.1770-4). Latching clip LEDs, live gain-reduction meters on every dynamics processor, a per-channel spectrum analyzer, and a stereo correlation meter on the master for mono-compatibility checks.

5-band Parametric EQ
Each channel includes a fully interactive parametric equalizer: LF Shelf, Low Mid, Mid, Hi Mid, and HF Shelf. Drag handles directly on the frequency display with the live signal spectrum rendered behind the curve, or scrub and type values numerically.

13 insert effects per channel
A fixed studio-style signal chain on every channel.
- Gate: threshold, attack, hold, release
- Expander: threshold, ratio, attack, release
- Compressor: threshold, knee, ratio, attack, release, makeup gain
- Tape Saturation: drive, warmth, dry/wet mix
- Distortion: amount, overdrive/distortion modes, dry/wet mix
- Delay: time or BPM-synced subdivisions, feedback, dry/wet mix
- Reverb: size, decay, dry/wet mix
- Chorus: rate, depth, dry/wet mix
- Flanger: rate, depth, feedback, dry/wet mix
- Phaser: rate, depth, feedback, dry/wet mix
- Vibrato: rate, depth
- Tremolo: rate, depth, sine/square shape
- Limiter: brick-wall ceiling, attack, release

Every effect has a bypass toggle, a real-time visualizer, factory presets, and right-click numeric entry on any parameter.

Automatic per-site presets
Your settings are saved automatically per URL - fader, pan, EQ, effects, everything. Return to the same page and your mix is restored exactly as you left it.

Master bus
A dedicated master channel provides global level, pan offset, and mute across all channels, with stereo metering and a full-width spectrum analyzer of the combined output.

Make it yours
Ten built-in color themes, including a light theme - plus a fully customizable accent color and adjustable UI zoom.

No data collection
Audio Console only requests the access it needs to find and process audio in your tabs. All processing happens locally, all settings are stored locally. No browsing history is collected, nothing ever leaves your browser.
