How it's made
Source
a platformer character pushing off the air a second time. Two short tonal glides stand in for the "boing" of the jump; a band-passed breath of pink noise stands in for the puff of air under the feet.
Body
each glide is a sine plus a quieter triangle one octave up (the 2nd harmonic adds brightness without harsh upper partials), swept upward by 1.1–2× in about 100–120 ms; the puff is pink noise band-passed at 2.5× the glide pitch (Q ≈ 0.9), so air and tone move together.
Envelope
4 ms soft attack, then a fall over 2–3 glide lengths. The second glide starts 70–180 ms after the first and begins higher (1.1–2×), which reads as "jump again". Each puff swells over ~40 ms.
Variation
`rng` detunes the pitch by ±1.5 % and nudges the gap by ±3 %. Parameters set pitch, the interval between the two jumps, glide size, airiness and brightness; presets change character.
