Reed Bed Sway

How it's made

Source

dry reed sheaths slide and catch as a lakeshore breeze bends adjacent stalks; filtered noise models papery friction at 900-6500 Hz, with overlapping 40-90 ms scrape attacks.

Body

hollow stalk contacts excite broad 420-950 Hz and 1.9/3.1-ratio wall modes; 22-75 ms damping gives woody ticks without a sustained pipe whistle or a musical pitch.

Envelope

irregular 5-12 second wind waves drive friction level, spectral opening and contact density together. Adjacent clumps lag 0.45 seconds; independent flutter adds fine surface motion.

Events

sheath brushes arrive at 2-9 per second, lasting 0.15-0.4 seconds; stalk contacts at 0.5-3 per second have 1.5-4 ms soft attacks and random tuning, strength and stereo placement.

Layers

low-level broad hollow friction at 380-1000 Hz under papery sheaths; no lake water, birds, sub-bass wind or reverberation. Two low-pass stages tame energy above 7 kHz.

Variation

breeze automates excitation; sway changes wave pace, paper changes sheath brightness, stalks changes contact density/body balance. Presets cover shelter, dry rattle, rushes and gusts.
