Static can mean anything from a thin phone-line hiss to aggressive TV snow. The quickest way to get a usable result is to describe the source, bandwidth, and how the noise should start and end. Use the guide below to choose prompts that cut cleanly, loop smoothly, and avoid overpowering dialog or music.
Name the source and channel
Start by stating what the static is coming from. The same noise feels different when it is a radio scan, a CRT with no signal, or a walkie-talkie squawk. Source cues steer the spectral shape and texture.
- Use words like AM radio, FM scan, CRT snow, phone line, intercom, walkie-talkie
- Ask for band-pass for comms, broadband for TV snow, or midrange grit for tuning
- Mention mono vs wide stereo to match the device or screen perspective
Control attack and tail for edits
Static often works as a cut-point effect, so describe how quickly it hits and how it stops. A hard stop is great for glitches, while a soft fade is better for beds under dialog.
- For stingers: sharp transient, fast attack, abrupt cutoff, no reverb
- For beds: soft fade in, steady noise floor, smooth fade out
- To avoid clicks: request clean start and clean end, or loop-friendly ending
Choose density and masking strength
Noise density decides whether the static is a subtle presence or an aggressive interruption. If your scene has speech, describe lighter density so consonants stay clear.
- Ask for low masking strength for dialog scenes and higher density for signal loss moments
- Mention controlled low-end to prevent rumble that muddies music or VO
- Specify occasional crackle bursts vs constant hiss to match the on-screen action
Avoid common prompt pitfalls
A few extra words can prevent unusable results. Static that is too tonal, too reverberant, or too dynamic can feel like a synth instead of interference.
- Avoid strong musical pitch unless you want an electrical whine layered in
- Skip large room reverb for device static, unless the device is heard from far away
- If it pumps: request steadier level, less compression, or smoother dynamics
