Why run an audio test

An audio test confirms that your speakers or headphones are playing correctly and that left/right channels are balanced before calls, streaming, or editing. It is a simple way to spot missing channels, low volume, or output issues without installing software.

How the test runs

The tool plays short tones through your browser using the current audio output. You can switch between left, right, and other tones to verify channel separation, and the test stops when you leave the page.

How to interpret results

Each tone should be heard from the expected side or speaker. If a channel is silent or quiet, the output device, system settings, or cables may be the cause. Use the tones to compare balance and confirm that both sides respond consistently.

No sound suggests muted output, wrong device, or blocked playback.
Uneven volume can indicate balance or driver settings.
Missing channels often point to cabling or device issues.

This test checks browser playback only and does not measure audio quality, frequency response, or microphone input.
