How it's made
- Source
- rapid expansion along a branching lightning channel, modelled with overlapping brown, pink and white noise packets, not pitched oscillators. Uneven arrivals span 0.03-3.7 s with 7-32 ms attacks.
- Body
- pressure energy occupies 32-300 Hz; broad 160-650 Hz noise adds rolling body without tonal modes. Air absorption lowers the upper cutoff from 0.9-3.8 kHz toward 230-650 Hz as arrivals recede.
- Envelope
- an initial 90-240 ms swell leads to irregular secondary surges, then a slow 3 s decay; the pressure bed reaches zero at 5.95 s. Crack packets decay in 0.055-0.19 s, body packets in 0.6-1.4 s.
- Space
- the channel traverses up to 1.8 stereo pan units over 4.7 s. Quiet, dark, decorrelated arrivals at 110 and 230 ms offsets represent multipath propagation, without a resonant indoor reverb.
- Variation
- named random streams vary arrival times, strengths, packet colours and fine spatial offsets. Distance controls absorption and attack softness; fracture controls clustered 480 Hz-3.8 kHz packets.
- Presets
- open-sky traverse, distant muffled thunder, close fractured thunder, and a broad reverse roll change absorption, fragmentation, secondary surges, travel width and direction.
