Audio Tests
Audio Tests on DeviceHub cover the full browser suite: microphone levels, speaker and headphone channel checks, stereo imaging, left/right wiring drills, best-effort surround orientation, mic monitoring delay estimates, local echo loops, relative noise metering, stepped volume checks, and bass/treble frequency tones. All analysis and synthesis stay on your device so you can validate hardware before calls, recordings, and listening sessions.
Start with Microphone Test or Speaker Test for everyday smoke checks, then use Stereo Test and Noise Level Meter when imaging or ambient floor matters. Specialized tools such as Echo Test, Mic Monitoring Delay Estimate, and frequency/bass/treble pages deepen troubleshooting without installing vendor utilities.
