How to use Generate Random Audio
- 1. Set the clip length and sample rate. Enter Duration (ms) for how long the clip runs, and Sample rate (Hz) to control audio quality, higher rates capture more detail but produce larger files.
- 2. Choose noise or a tone. Turn on Random tone instead of noise to generate a single random-frequency tone, or leave it off for full-spectrum random noise across the clip.
- 3. Generate the clip. Click generate to produce a WAV file built entirely in your browser from the settings above, no external audio library or server involved.
- 4. Download the file. Download the resulting WAV file to use it locally. Regenerate for a differently seeded clip at the same settings.
When to use Generate Random Audio
Generate Random Audio creates a short WAV clip of noise or a random tone entirely in the browser, useful whenever you need throwaway audio for testing without recording or sourcing a real sound file.
- Testing an audio player component. A developer building a web audio player wants a quick WAV file to confirm playback, waveform rendering, and volume controls all work before wiring up real content.
- Checking a file upload pipeline. Someone testing an app that accepts audio uploads wants a small sample WAV file that does not require licensing or downloading a stock sound effect.
- Generating a placeholder alert tone. A developer prototyping a notification system wants a short random tone to stand in as a temporary alert sound before a designer supplies the final one.
- Producing white noise for a quick demo. Someone building a sleep or focus app demo wants a short burst of noise to show how the playback controls behave with continuous audio.

About the Generate Random Audio tool
Generate Random Audio runs as plain JavaScript in your browser tab, with no server behind it. Create a random WAV audio clip. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's Random Tools section, 120 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
You can shape the output with 3 settings, including Duration (ms), Sample rate (Hz) and Random tone instead of noise, and the result refreshes the moment you change one. The finished file is put together in browser memory and saved with the Download button, so it never touches a server on the way to your disk. 2 worked examples further down the page show exactly what the tool produces for real inputs.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
Frequently asked questions
Is Generate Random Audio free to use?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Does the generator send anything to a server?
Everything happens locally. Your browser downloads the tool's code once, then does all the processing itself; nothing you enter is transmitted, stored or logged. You can even go offline after the page loads and it will still work.
How do I get a different result?
Run the generator again. Each run is computed fresh on your device, and any options you change are applied to the next result immediately.
Do I need to sign up or install anything?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
How do I save the output?
Click the Download button once the result is ready. The file is built in your browser's memory and handed straight to your downloads folder, without passing through a server.
