Test Utilities
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, or 20 Hz → 20 kHz sweep) 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.

how to use
- ▸ 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.
