Frequently Asked Questions
No, our audio testing tools run directly in your web browser. You don't need to download or install any software. You just need a modern web browser like Chrome, Firefox, Edge, or Safari.
For microphone testing and some advanced speaker tests (like latency tests), our tool needs access to your microphone to analyze the audio input. We don't record or store any audio - all processing happens locally in your browser.
Yes, our tools are designed to work on mobile devices as well as desktop computers. The interface will adapt to your screen size. Some advanced testing features may work better on desktop browsers due to Web Audio API implementation differences.
The frequency sweep test plays a tone that gradually changes from low frequencies (20Hz) to high frequencies (20kHz). This helps you check if your speakers or headphones can reproduce the full range of human hearing, and identify any frequencies where your audio system has issues.
Our tests provide a good general assessment of your audio equipment. However, for professional audio work, we recommend professional calibrated equipment. The test accuracy depends on your browser, hardware, and environment. The results should be viewed as informative rather than definitive measurements.
