Noise is only useful when it matches the moment: a sharp static jab for a cut, a stable hiss bed for room tone, or a narrowband squelch for comms. Use prompts that describe spectrum, movement, stereo width, and tail behavior so the clip sits where you need it without fighting dialogue or music.
Choose the noise color and bandwidth
Start by naming the spectrum you want. Broadband static masks aggressively, while pink or tape hiss sits smoother under speech. Narrowband interference sells radios and devices.
- Use words like broadband, narrowband, warm, bright, or midrange gritty
- Call out white noise, pink noise, tape hiss, or radio interference explicitly
- If it feels too sharp, ask for reduced harsh highs or softer top end
Control movement, attack, and tail
Editors usually need either a tight hit or a controllable bed. Specify how quickly it starts, whether it pulses, and how it ends so it does not step on the next line or beat.
- For cut hits: sharp attack, quick decay, short tail
- For beds: steady level, subtle movement, loopable timing
- For glitches: transient spikes, bitcrushed texture, abrupt cutoff
Match stereo width to the picture
Stereo width changes perceived size. Wide static feels like a screen, while centered noise feels like a handheld device or close mic issue. Describe width so it matches the source in frame.
- Ask for wide stereo shimmer for TV or broadcast moments
- Ask for centered or mono-ish noise for radios and close foley
- If it blurs the mix, request narrower stereo or less side energy
Avoid common prompt mistakes
A few extra words prevent unusable results. Noise that is too loud, too tonal, or too clicky can distract from dialogue and make looping obvious.
- Say no voices, no music, no beeps if you only want noise texture
- Ask for clean loop edges if you plan to repeat it under a scene
- Request no loud pops if you need vinyl-style crackle without spikes
