How it's made
- Source
- spent brass casings striking a hard floor; 0.2 ms attacks and 1-3 ms filtered noise contacts.
- Body
- thin cylindrical walls ring at inharmonic ratios 1, 1.47, 2.19, 2.83 and 3.76 of 1.7-2.7 kHz. Modal T60 is 65-270 ms, with upper modes dying first; a 700 Hz contact layer adds floor weight.
- Envelope
- 6-8 bounces per casing, initial flights 260-330 ms, each flight about 72% of the last. Impact amplitude falls geometrically; late contacts darken and shorten as energy is lost.
- Layers
- dry contact ticks, five shell modes, and faint 8-16 ms sliding friction after late contacts.
- Variation
- each casing keeps its own tuning and stereo position; orientation changes modal balance, timing by 6%, and strength by 12%. No pitch glide or room reverb is added.
- Presets
- isolated casing, three scattered casings, a larger lower shell, and bright tile skitter.
