Radio Static

How it's made

Source

receiver noise between stations; white thermal hiss plus quieter pink atmospheric noise. Dense bipolar impulses model fine electrical hash; irregular noise packets model interference.

Body

one mono radio loudspeaker, high-passed at 160 Hz and low-passed at 2.6-8.2 kHz, Q 0.6. A broad 1.5 kHz emphasis colours the atmospheric layer without a ringing cabinet resonance.

Events

2-16 interference packets/s, with 0.4-1.2 ms attacks and 3-22 ms exponential releases; strength squared favours small ticks with occasional stronger crackles, not hard digital cuts.

Modulation

independent 0.24-0.9 Hz drift changes gain, noise bandwidth and packet density. Two faint heterodyne difference tones wander near 1.2 and 2.3 kHz and fade independently.

Envelope

a continuous bed, with at most 25 percent slow gain movement; no station or speech emerges. The renderer crossfades the six-second loop seam; no start/stop envelope interrupts the bed.

Variation

seeded streams vary hiss, packet timing, strength and whistle drift. Bandwidth, interference, whistle and fading controls yield wideband hiss, a narrow receiver, electrical hash or shortwave fading.

Space

dry and mono, as emitted by a single receiver speaker; no room or artificial stereo spread.
