Dumperator is a professional profanity delay that runs on the Windows PC you already have. Thirty seconds of protection, seamless crossfades, and one big button that dumps it all back to real time — instantly.
Free to download and fully functional · US$99 one-time licence removes the demo beep
A guest drops an f-bomb, a caller goes off script, a live interview takes a turn. Without a delay, that moment is on air forever — and the fine lands on your licence, not on the person who said it.
A purpose-built rack delay runs from around US$1,500 used to over US$4,000 new. For a small station, a community broadcaster or a podcast studio, that is a hard number to justify.
Another 1U box, another power supply, another set of XLR runs, another thing to fail at 2am. And it does exactly one job.
Plenty of shows just run live and hope. That works right up until the moment it doesn't — and one incident costs more than the box ever would have.
Dumperator sits between your audio input and your audio output, holding a rolling buffer of everything you've said. Nothing reaches air until it's too late to take back.
Choose a WAV file — music, a jingle, a station ident, anything. Its length becomes your delay time. A 20-second bed gives you a 20-second delay; a 30-second bed gives you the maximum 30 seconds.
Dumperator crossfades smoothly from your live feed into the filler, then slides into the delayed feed. Listeners hear music instead of a click, and your delay is now live.
When something shouldn't go to air, hit DUMP. The filler and the delayed audio crossfade back to real time over one second, and the moment is gone. You're live again.
No menus you'll never open. No subscription. No cloud. Just the controls you need, on screen, ready.
Every transition is a smooth equal-length crossfade, not a hard cut. Your listeners never hear the seam when you enter or exit delay.
When you're not in delay, audio passes straight through untouched. Dumperator is invisible until you need it.
The DUMP button is armed whenever you're in delay — and so is your spacebar. Reach for whichever is faster. On air, half a second matters.
Pick your audio devices from a list of everything Windows can see — mixer feeds, interfaces, virtual cables. Mono or stereo is detected automatically.
Your device selection and filler file are saved. Open the app on air day and it's already where you left it.
Everything runs locally on your machine. Your audio never leaves the building, and there is nothing to log into before a show.
Hardware delays are excellent — and priced for network budgets. Dumperator does the job on hardware you already own.

On hardware pricing: real-world prices for broadcast profanity delays run from roughly US$1,500 for used units up to US$3,999–US$4,499 for new Eventide BD600-series boxes. Dumperator doesn't try to match a broadcast-grade rack unit feature for feature — it does the core job, on your PC, for US$99.
No subscription. No expiry. No per-show fees.
How buying works: download Dumperator, open it, and register from inside the application. There's no checkout page and no account to create — you pay once and the beep stops. Your licence is tied to a single Windows PC.
Up to 30 seconds. The exact figure is set by the length of the filler WAV file you load — Dumperator calculates the duration of the file and that becomes your delay time. Load a 12-second jingle and you get a 12-second delay; load a 30-second music bed and you get the full 30.
The 30-second ceiling is deliberate. It keeps memory use predictable so Dumperator can run safely alongside your playout software on the same machine.
The length, not the file size. Dumperator reads the audio and works out how many seconds it plays for. A short file with a high bitrate is fine; a long file is not, even if it's small.
Your filler audio. When you press START DELAY, Dumperator crossfades from the live feed into the filler over one second, then moves into the delayed audio. Listeners hear your chosen music or ident while the buffer fills — no dead air, no click.
Dumperator crossfades from the delayed audio back to the live feed over one second and drops the delay. Whatever was in the buffer never goes to air. You're back to real-time passthrough and can start a new delay whenever you like.
So you can try the whole thing properly before paying. The free version is fully functional — full delay, full crossfades, full DUMP — but plays an audible beep every 15 seconds, which makes it unusable on air. Registering removes the beep permanently.
You get a permanent licence for one Windows PC, with the beep removed. It's a one-time payment — no subscription and no renewal.
What it doesn't include is upgrades. Your licence covers the version you buy. If a future version is released, it isn't included and would need to be purchased separately.
The licence covers one Windows PC. If you need it on a second machine — a studio machine and a backup, say — you'd need a second licence.
No. Dumperator runs entirely on your machine and processes audio locally. Nothing is uploaded, streamed, or stored off-site, and there's no account to sign into.
Anything Windows exposes as an input and an output — physical interfaces, mixer feeds, and virtual audio cables. Dumperator detects mono or stereo automatically and shows you what it found.
One thing to note: your input and output devices generally need to use the same audio driver type (for example, both WASAPI). Dumperator warns you clearly if the combination won't work.
Download Dumperator, pick your input and output, load a filler file, and you're protected. Free to try for as long as you want.
