1. Environment
Runs by itself when the page opens. Press to run again.
2. Audio files
Pick one or more music files (MP3, M4A, FLAC, OGG, WAV). Each is decoded, timed, and saved into the browser's private storage, then read back. The last decoded file plays during the XR test.
3. Microphone
Press "Test microphone" and allow access. Then play music near the headset. The yellow block flashes on each detected kick drum.
4. Speaker-to-mic delay
Turn the headset volume up and keep the room quiet. It plays 10 clicks, one per second.
5 + 6. Room data in XR, and music in XR
Music starts first (your picked file, or a 120 bpm beat), then the headset goes into passthrough. Look around: coloured outlines show the walls, floor and furniture the headset knows. A panel in front of you shows the counts. If it says "No room scan", pinch once. Open the system menu once, then take the headset off for 10 seconds and put it back on. Exit with the Meta button.
