Frequently Asked Questions

Why is there no sound?

1. Check your system volume.
2. Ensure the browser tab is not muted.
3. iOS/Android users: Ensure your physical silent switch is off, as it can mute Web Audio API sounds.

Why test Left/Right channels?

Accurate stereo imaging is crucial for music production and gaming (hearing footsteps). This test confirms your speakers are positioned correctly and wired properly.

What is a Frequency Sweep?

This plays a tone that slides from the lowest audible bass (20Hz) to the highest treble (20kHz). It helps identify the limits of your speakers and any crossover issues.
