Speaker test
Click any speaker, drag to pan, or run the full surround sequence — verifies channel routing on stereo, 5.1, and 7.1 systems.
A room diagram with each speaker positioned where it sits in a typical install. Click one to fire pink noise (or a 1 kHz sine, click train, sweep, or demo arpeggio) at only that channel. Drag inside the room to pan the signal continuously, or hit "test all in order" to walk every channel — the standard verification for an AVR / processor's discrete output. Detects your device's available channel count and disables surround if the connected output is stereo-only. Web Audio defines no 7.1 channel order, so a side/rear swap is provided.
check your system volume before testing — signals fire the moment you click a speaker
- ▸ Click any speaker on the room diagram to fire that channel only. Pink noise is the universal choice for verifying coverage and tonality.
- ▸ Hold and drag inside the room to pan the signal continuously — useful for checking that the transition between adjacent speakers is smooth.
- ▸ Test all in order walks every speaker until you press Stop. Sweeps get the full 6 s per channel; everything else is ~1.5 s.
- ▸ Headphones mode routes each channel through an HRTF panner so AirPods / headphone listeners hear virtual 5.1 or 7.1 over stereo. Switch it off when you're actually wired into a multichannel AVR or USB DAC and want discrete output.
- ▸ 7.1 caveat: Web Audio only standardises channel order up to 5.1. On an 8-channel device, which physical output carries "side" vs "rear" is decided by the OS driver and the AVR's input map. If the wrong pair lights up, use Swap side / rear in the layout section.
