∞FX OS

Build your own effects box from 60+ real-time audio effects in 8 families: drive and fuzz, modulation, delays and reverbs, filters, dynamics, pitch, spectral experiments and analysis tools. Chain up to three, pick a wood or finish (which gently voices the tone), name it, colour it, then hear it on a riff synthesised right here or on your own mic or line input. Nothing makes a sound until you press a button.

    Creator Pick effects, shape the knobs and the look, and listen as you go. Or let the cyclers and ∞ cycle surprise you.

              ∞ Roadmap Every effect here is a plug-in module, so new techniques drop straight in. These are the ones that are too heavy, too large, or not possible in a browser yet, and why.

              • Neural amp and pedal capturesMachine-learning models (NAM / AIDA-X style) of real amps and drives.Needs a WebAssembly neural runtime and multi-megabyte model files: heavy on phones.
              • Measured cabinet and room IR librariesHundreds of real speaker cabinets, rooms and vintage plates.The IRs here are generated on the fly; real ones are large downloads with licensing to sort out.
              • Studio-grade polyphonic pitchClean pitch shifting and correction of chords (phase vocoder / PSOLA / POG-style octaves).The worklet shifters here are honest grain-based ones: great on single notes, warbly on big chords.
              • High-band vocoder with real formants40+ band vocoder with formant tracking and a built-in carrier synth.The 12-band vocoder here is real but light so it runs on phones.
              • FFT spectral freeze and morphingFreeze, blur and morph between two sounds in the frequency domain.Needs an FFT worklet; the freeze here is grain-based.
              • Measured rotary-speaker modelsA Leslie built from recorded horn and drum responses.The rotary here is modelled with modulated delays and filters.
              • Hosting third-party plug-insLoad Web Audio Modules (WAM 2.0) plug-ins from other developers as boxes.Needs a vetted plug-in list and a stricter security review first.
              • Tempo sync and MIDI controlLock delays and pumps to MIDI clock; turn knobs from a MIDI controller.Web MIDI is not available in every browser (notably iOS Safari).
              • Processing the site's Bandcamp and SoundCloud playersRun the tracks on this site through your box.Not possible: browsers don't let one site touch audio inside another site's embedded player.
              • AI stem separationPull the guitar out of a full mix and process only that.Large models, slow on phones, and it still can't reach the embedded players.
