About the Hz Test Tone Generator
The Hz Test Tone Generator plays a steady tone at an exact frequency you choose — useful for calibration, tuning and testing a specific problem. It runs as plain JavaScript inside the page, which means there is no upload step, no queue and no size limit imposed by a server — the only limit is your own device.
What people use it for
- Producing a 1 kHz reference tone for level setting.
- Checking a specific frequency a speaker seems to struggle with.
Start with the volume low and raise it slowly. Sustained pure tones are far more damaging to hearing than music at the same apparent loudness, and asking a small speaker to reproduce very low or very high frequencies at volume can damage the driver.
Frequently asked questions
Why is 1 kHz the standard reference?
It sits in the middle of the range where hearing is most sensitive and where most equipment is flattest, which makes it the fairest single point for comparing levels.
Is the Hz Test Tone Generator free?
It is free, with no account, no trial and no daily cap. Every audio tests tool on inputtesthub.com works the same way: open the page and use it.
Can you see what I put into this page?
No. The Hz Test Tone Generator runs entirely in your browser using JavaScript. Because the work happens locally, the page also keeps working if your connection drops, and closing the tab is all it takes to discard everything.
What problem does the Hz Test Tone Generator solve?
The most common reasons people reach for it: producing a 1 kHz reference tone for level setting. Checking a specific frequency a speaker seems to struggle with. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Any caveats I should know about?
Start with the volume low and raise it slowly. Sustained pure tones are far more damaging to hearing than music at the same apparent loudness, and asking a small speaker to reproduce very low or very high frequencies at volume can damage the driver.
Do I need to install anything to run this test?
No installation, no extension and no driver. The Hz Test Tone Generator uses the browser's own device APIs and begins as soon as the page loads, so there is nothing to press first. Press Reset at any point to start over with a clean slate.
