About the Audio Balance Test
The Audio Balance Test alternates between channels so you can hear whether one side is quieter, and adjust the balance control accordingly. 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
- Setting the balance control when one ear or one speaker is weaker.
- Checking whether an accessibility balance setting is still applied.
Frequently asked questions
One side sounds quieter but the test says both are playing.
Check the balance slider in your system sound settings first — accessibility tools and some games change it and do not put it back. If balance is centred and one side is still quieter, the speaker or driver is the likely cause.
Are there any usage caps on the Audio Balance Test?
No charge and no sign-up. There is no free tier to run out of because there is no paid tier — inputtesthub.com is funded by advertising rather than by metering the page.
Does anything I enter leave my computer?
No. The Audio Balance Test 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 do people use the Audio Balance Test for most?
In practice it gets used for three things: setting the balance control when one ear or one speaker is weaker. Checking whether an accessibility balance setting is still applied. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Do I need to install anything to run this test?
No installation, no extension and no driver. The Audio Balance Test 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.
