TV Static

How it's made

Source

an untuned analog television receiver; white noise models continuous demodulator hiss, with independent dense bipolar impulses for the fine grain of electrical snow.

Body

a small mono speaker removes energy below 170 Hz; a broad 1.8 kHz pink-noise layer adds body. A low-Q 4.2-11.8 kHz low-pass sets speaker bandwidth without a sharp ringing resonance.

Layers

field-rate interference has 50/60 Hz harmonics through 600 Hz; low fundamentals are weak. A faint 15.625/15.750 kHz sine represents scan leakage, far below the broadband snow.

Modulation

field-rate amplitude ripple roughens the hiss; 3-7 Hz flutter and 0.7 Hz seeded wander gently move its level and bandwidth. The picture never resolves into speech or a station.

Envelope

continuous sustain; 50/60 Hz buzz and flutter complete whole cycles in the six-second loop. The renderer crossfades noise at the seam; there are no abrupt gates or isolated crackle transients.

Variation

seeded noise, drift and flutter phase; brightness, scan buzz and flutter control the layers. Presets offer bright snow, a small dull speaker, rolling interference and a 50 Hz receiver.

Space

dry mono, matching one television loudspeaker; no room tail or artificial stereo width.
