A 3.5-second double bass hit in E: a heavy downbeat and a softer answer, "DUM-dum". The first hit lands on frame 0 and carries the weight: a deep sub boom whose pitch falls from about 72 Hz to E1 (41 Hz), a soft felt-and-wood thud, and a gently saturated low layer that puts the weight into the 80-250 Hz range, so it still feels heavy on laptop and phone speakers. With it, a warm, wide E add9 chord (E2, B2, F#3, G#3, B3) of filtered analog-style saws blooms open. Half a second later, on frame 15, a lighter second hit answers a fifth higher, on B1, with its own short thud and no new bloom. A faint glassy shimmer on E5 and B5 rises out of the chord, and both hits ring down in a soft, dark room to silence at 3.5 s. Calm, confident and weighty, never harsh.

- Frame 0: heavy E hit
- Frame 15: lighter B answer
Two hits, accent on the first ('DUM-dum'): a heavy E1 downbeat on frame 0 with the E add9 bloom, then a lighter answer a fifth up on B1 on frame 15 with no new bloom. The first sub is choked just before the answer (like a re-struck drum) and the chord ducks briefly so the answer reads cleanly. Saturated 80-250 Hz layer keeps weight on laptop/phone speakers (-4.2 LU at a 150 Hz high-pass). Written as an original sting, not a sound-alike of any brand's audio logo; it's the site's own landing sound.
