Record a few seconds of anything — your voice, a clap, a passing train — and let the app pull it apart in time. What about phase? is a pocket instrument for process music: it loops your recording in two channels and lets them drift out of sync, so simple sounds grow into shifting, hypnotic patterns. Inspired by the tape-phasing experiments of 1960s minimalism, it makes the process itself audible — you set it in motion, then listen as it unfolds. TEN PROCESSES • Phasing — two copies of your loop, one drifting a few cents faster; hear them separate into echo, then canon • Gradual process — a ramp that grows louder and sweeps across the stereo field • Tape loop multiplication — your loop fanned into a detuned chorus • Rhythmic construction — a rhythm assembled hit by hit • Pattern substitution — beats replaced one at a time: silence, octaves, fifths • Resultant patterns — two interlocking rhythms revealing a third • Clapping Music — a pattern rotating against its fixed copy • Pulse / drone — a pulse grid over a deep foundation • Canon — staggered voices entering one after another • Speech melody — a syllable pulsed in speech rhythm and dynamics THE WHEEL A radial display shows what the process is doing: your loop's waveform — or the process's own pattern — wrapped around a circle, left channel in coral, right in cyan, a comet sweeping the playhead. In Phasing you can watch the two rings physically drift apart. Volume and pitch views included, with on-device pitch detection. AUDIO UNIT (AUv3) Every process also comes as an AUv3 plugin for AUM, GarageBand and other hosts: an instrument that plays the process's own demo, and an effect that does the process to whatever you send it. The wheel is the plugin's screen. Each voice has an output of its own, a MIDI note starts the loop over, and Sync can follow the host's transport. A Level control sets how loud every output is, and on the effects BAR sets the loop to one bar of your host's tempo and keeps it there. Look for the maker "Scriptum" in your host. The plugin is part of Pro, a one-time in-app purchase that also includes everything in the full version. Until Pro is unlocked the plugin loads and shows its wheel, but stays silent. MADE FOR EXPLORING • Ten built-in demo takes, one per process, playable from the very first launch • Every take saves with its process and settings; rename, share as WAV, revert • Takes named after where you record them (optional, location used only while in the app) • Live controls: drift in cents, process amount, tempo, sample offset • No account, no ads, no analytics — recordings never leave your device unless you share them Record something small. Let it become something long.
