High Voltage Line

How it's made

Source

damp overhead conductors sustain corona microdischarges: filtered impulse grains and 1–12 ms noise bursts over an airy 0.9–8 kHz ionization hiss, not large electrical arcs.

Body

coherent mains-related pressure hum at 100/120 Hz dominates weaker 50/60, 200/240 and 300/360 Hz partials. Broad filters colour discharges without ringing metallic resonances.

Envelope

continuous operation, with 0.2–0.7 Hz random moisture wander linking discharge density, hiss brightness and level. Hiss has shallow twice-mains modulation from field-magnitude cycles.

Events

3–28 irregular bursts/s and 250–2050 fine grains/s at full moisture; smooth sub-ms attacks and exponential releases keep the small discharges crisp without hard full-band clicks.

Space

independent left/right discharge beds surround a centred hum; distance absorbs high frequencies and narrows the image. No indoor reverberation or wind-driven wire singing is added.

Variation

named random streams vary burst length, colour, strength and pan. Moisture controls activity; hum and air set layer balance. Presets cover wet close lines, mist, distance and 50 Hz.

Loop

8 s contains whole 50/60 Hz mains periods; the renderer crossfades stochastic seam content.
