Incoming Call Loop

How it's made

Source

a synthesized glass-bell voice, struck by a very short soft click (1–2 ms) at every note of a ringtone phrase; no sustained excitation, so every note is an independent decaying strike.

Body

each note is a fundamental plus stretched partials (2.0×, 2.76×, 5.4×) and a faint octave-down body tone; upper partials decay 2–6× faster, so the attack is bright and the tail pure. A second, slightly detuned copy (+3 cents) of the fundamental beats slowly and adds shimmer.

Envelope

notes come every 0.09–0.16 s and overlap while ringing 0.25–0.9 s. A phrase of 8 notes is played twice per ring burst ("ring-ring"), then silence until the period ends (2.4–4 s), so the burst tail has died away before the next period starts and the 6 s loop holds whole periods.

Spectral movement

the first note of each group is accented, and a softer hit excites fewer upper partials, so the brightness of each strike follows its strength.

Variation

`rng` detunes each note by ±0.15 % and jitters its level by ±8 %; presets change phrase, register, tempo and brightness.
