Microphone test
Local input analysis
Microphone capture
StatusMicrophone access has not been requested.
Inspect the selected browser input, its actual settings and a short local recording without uploading raw audio.
Interpretation: The test can confirm that the selected browser input produces a digital signal and expose settings the browser reports. Limit: An uncalibrated microphone in an arbitrary room cannot establish true SPL or isolated microphone frequency response.
Safety and privacy: Microphone access starts only after you grant permission. Analysis and short recordings stay in this browser by default; raw audio is not uploaded. Digital dBFS is not physical SPL.
How to use this test
- 1.Grant permission deliberately: WaveLocus requests microphone access only after you press the permission button.
- 2.Speak at the normal distance: Watch peak, RMS, clipping, waveform and spectrum without treating dBFS as physical loudness.
- 3.Check actual processing: Compare the requested processing state with the settings the browser actually reports.
- 4.Make a short local recording: Record up to ten seconds, stop the live track and play the temporary local clip back.
