Command

$ sb get AXJ7QCV9D3@1 --preset air -o downlifter.wav

Source: three layers. A pink-noise air bed, a pair of slightly detuned saw oscillators gliding down in pitch (the tonal "fall"), and a soft sub sine that follows the pitch an octave lower for weight.
Body: the noise passes a resonant low-pass whose cutoff falls exponentially from the bright start to a dark floor, a descending filter sweep. The saws pass a second low-pass that closes with the same curve, so the harmonics vanish as the pitch drops and nothing stays harsh.
Envelope: a soft 25 ms onset avoids a click, a short hold, then a long decrescendo (curved release) into silence; the sub fades slightly earlier than the noise so the tail is airy and dark.
Variation: length, start brightness, tonal amount, sweep depth and stereo width; `rng` shifts the saw detune and the noise stream slightly.
