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. 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.
