How it's made

Source
a futuristic terminal's rejection cue: two synthesized beeps (a square-ish pair, a few cents apart, plus a sine fundamental) that step down by a fourth, then a short sawtooth buzz from a cheap driver.
Body
a small speaker cabinet rolls the beeps off above 2–4 kHz (low-pass) and adds a gentle 1.2 kHz presence bump; the buzz is two detuned saws at about 1/7 of the beep pitch, amplitude-chopped at 55 Hz and low-passed at 0.9–2.6 kHz so the rasp stays tolerable.
Envelope
each beep is ~0.11 s with 4 ms ramps (no clicks) and a 25 ms gap; the buzz runs 0.08–0.25 s and is then cut by a 6 ms gate (the "firm stop") with a 90 Hz sine thump decaying in 60 ms, like a relay closing.
Variation
`rng` mistunes the oscillator pairs by up to ±8 cents; presets move pitch, interval, buzz length and darkness (strict console, cheap gadget, deep vault, snappy).
