Line Clear

How it's made

Source

a full row of blocks vaporising in a falling-block puzzle. Three layers: an electrical zap that sweeps across the row, a cascade of glassy sparkle pings, and a pitched tail that falls as the row empties.

Zap

a band-limited saw plus a detuned square sweep exponentially from 300 Hz to about 3 kHz in 0.16 s through a low-pass that opens with the pitch (cutoff 2.5x pitch), with a 4 ms onset and a 0.1 s release.

Sparkle

4-12 sine pings with a 2.01x inharmonic partial, 2.4-6 kHz, spaced 25-45 ms from the zap peak and descending in pitch like the cleared blocks falling away; each rings 80-220 ms with a 2 ms attack.

Tail

a sine glide from 1.4 kHz down to a quarter of that over 0.5 s with a faint octave-up shimmer; it carries the "descending" impression and ends well inside the 0.8 s target.

Envelope

zap 0-0.3 s, sparkles 0.1-0.6 s, tail 0.1-0.7 s; the master fades to zero at the end.

Variation

`rng` detunes every ping by +-2 % and jitters timing; macros set sweep speed, sparkle count, brightness and tail length; presets move between arcade, glassy, soft and heavy clears.
