Browser FX: Tab Audio Effects + MIDI

Real-time audio effects for any tab: reverb, filter, EQ, bitcrusher, delay + 17 more. Chain 4 effects, presets, MIDI control.

Browser FX transforms your web audio experience with real-time professional audio effects. Capture any tab's audio, chain up to 4 effects, and shape the sound with studio-style knobs, an audio-reactive cymatic visualizer, and hands-on control from your MIDI controller. 22 HIGH-QUALITY EFFECTS: Bitcrusher • CD Skipper • Reverb • Hall Reverb • Filter • Auto Filter • Comb Filter • Delay • Tap Delay • Distortion • Chorus • Phaser • Flanger • Tremolo • Vibrato • Auto Panner • Pitch Shifter • Ring Mod • Compressor • DJ EQ • Tape Stop • Lo-Fi Tape EFFECT CHAINS: Stack up to 4 effects and run them in series: bitcrush into reverb, filter into delay into tape. Drag to reorder the chain, switch each effect on and off without a click or pop, and even double up the same effect for extreme sounds. PRESETS: Seven presets to start from: Lo-Fi Radio, Chopped & Screwed, Wobbler, Warped Record, Jet Stream, Dub Echo and Cyborg. Load one and turn some knobs, then save the result as your own. Your presets store their MIDI mappings too, so loading one brings back your controller layout along with the sound. MIDI CONTROL: Map any MIDI controller with one-click MIDI learn: knobs control parameters, pads and buttons punch effects in and out. Mappings stick to each effect (even when you reorder the chain), and your controller keeps working with the popup closed.
