TV Static & White Noise, Right in Your Browser
TV static is the snowy "no signal" screen analog televisions showed when there was nothing to tune in to. This tool recreates that effect full-screen in real time, complete with scan lines, glitch interference, a darkened vignette, and an optional white noise hiss to match.
It is built for anyone who wants the look and sound on demand — filmmakers grabbing a quick effect, streamers and pranksters faking a dead channel, retro fans chasing nostalgia, or people who simply find the steady static soothing to focus or fall asleep to. Pick a color tint, adjust the grain and intensity, and your settings are remembered for next time.
How to Use the TV Static Screen
Watch the static
The TV static effect starts the moment the page opens — a full-screen field of flickering snow with a flickering NO SIGNAL overlay.
Turn on the sound
Click the Sound button to play ambient white noise. Browsers block audio until you interact with the page, so this first click is what lets it through.
Open Settings
Click the gear icon to open the Settings panel, where every part of the static and audio can be tuned.
Customize the effect
Pick a Color Tint, set Grain Size and Intensity, toggle Scan Lines, Glitch Lines, and Vignette, and set the Volume. Use Reset any time to return to the defaults.
Features
Realistic TV Static
Randomized pixel snow is drawn on a full-screen canvas in real time, closely matching the static of an analog CRT television.
White Noise Audio
Ambient white noise is generated in your browser with the Web Audio API — a steady hiss to pair with the static.
Five Color Tints
Switch the snow to B&W, Green, Blue, Amber, or Red for a classic, phosphor, or warm retro-monitor look.
Adjustable Grain Size
Slide the grain from fine 1-pixel noise up to coarse 8-pixel blocks for finer detail or a chunkier pattern.
Intensity Control
Set how fast the static refreshes, from a slow subtle flicker to an intense pattern running at up to 60 frames per second.
Scan Lines
Overlay horizontal scan lines that mimic the way a CRT monitor draws its picture, toggled on or off as you like.
Glitch Interference
Random horizontal strips shift and flash to simulate signal interference, adding life and realism to the snow.
Vignette Edges
A radial gradient darkens the screen edges for the soft light falloff of an old television set.
Flickering NO SIGNAL
A flickering NO SIGNAL overlay fades in and out periodically, just like a real set tuned to a dead channel.
Volume Control
A dedicated slider sets the level of the white noise so the hiss sits exactly where you want it.
Settings Remembered
Every choice — tint, grain, intensity, toggles, and volume — is saved in your browser and restored on your next visit.
Auto-Pause
When you switch to another tab, the visuals and audio pause to save CPU, then resume instantly when you return.
One-Tap Reset
A single Reset button returns the tint, sliders, and effect toggles to their defaults whenever you want a clean slate.
Frequently Asked Questions
What is TV static and what causes it?
TV static — the "snow" on a screen — is the random visual and audio noise an analog television shows when it receives no broadcast signal. With nothing to tune in, the set amplifies background radio noise into flickering dots and a steady hiss. This tool recreates that look and sound digitally, no antenna required.
Why can't I hear the white noise?
Browsers block audio from playing on its own. Click the Sound button to start the white noise — that interaction is what allows audio through. If it is still silent, check that your volume slider isn't at zero and that your device isn't muted.
Can I change the color of the static?
Yes. Open the Settings panel and choose a Color Tint: B&W for classic snow, Green for a phosphor monitor look, Blue, warm Amber, or Red. The tint is applied to the noise live as you select it.
What's the difference between grain size and intensity?
Grain Size controls how big each speck of static looks — from fine 1-pixel noise to coarse 8-pixel blocks. Intensity controls how quickly the snow refreshes, from a slow subtle flicker to a fast, frantic pattern. Together they let you dial in anything from a calm shimmer to a harsh storm of static.
Is white noise good for sleep or studying?
Many people use steady white noise to mask sudden background sounds, which can make it easier to relax, focus, or drift off. This tool gives you that even, broadband hiss on demand. It is meant for general listening and ambiance, not as medical or sleep advice — use whatever volume feels comfortable.
Will this use a lot of battery or CPU?
The effect automatically pauses when you switch to another browser tab, so it won't keep running in the background. At lower intensity it stays light on resources; higher intensity combined with fine grain redraws the screen far more often and will use more CPU and battery.
Are my settings saved?
Yes. Your tint, grain, intensity, effect toggles, and volume are stored in your browser's local storage and restored automatically the next time you open the page. Nothing is sent to a server, and the Reset button clears them back to the defaults.
