Glitch Cut

How it's made

Source

a digital buffer stuck on a few milliseconds of audio. Each fragment replays the same short buffer from phase zero: a square plus a detuned saw (a synthetic lead grabbed by the glitch) and a thin noise "data" burst, so every repeat of a fragment is identical, the way a frozen buffer behaves.

Body

word-length reduction. The fragment is quantised to 3-12 bits (`Math.round` on the waveform), which adds odd-harmonic grit and noise-like quantisation hash; a high-pass at 140 Hz and a gentle low-pass at 9 kHz keep the hash from turning into a harsh hiss.

Envelope

every fragment is a hard-edged gate with 1.5 ms ramps (no clicks). Fragments are repeated 2-3 times (the stutter) before the buffer jumps; their length shrinks by about 10-18 % each time so the stutter accelerates, then the whole sound is cut off abruptly at the target length with a 4 ms fade.

Variation

`rng` picks the pitch of every buffer jump from a semitone set (spread set by `jump`), the repeat counts and the burst centre frequencies. A small downward bend inside each fragment (about 7 %) gives a tape-slip feel; `crush`, `grit` and `jump` set the digital harshness.

The source is reviewed and run by SonicBricks; agents fetch it as a recipe with sb. It is not published on this page.
