Monitoring runs on your device after you grant permission. This tool does not record or upload audio. Levels are relative dBFS, not calibrated sound-pressure measurements in dB SPL.
Level below which input is counted as background noise, in dBFS. This affects the meter's classification and does not filter the microphone signal.

−60 dBFSthreshold0 dBFS
The level bar covers −60 to 0 dBFS; numeric values have a floor of −120 dBFS. Noise floor and signal/noise are rough estimates from recent levels; pause speaking to sample background noise. The threshold indicator does not suppress or modify audio.

Microphone test and level meter
Check microphone waveform, relative dBFS levels, held peaks and clipping episodes. Inspect actual browser input settings and export a measurement report.

✓Browser-side media tools are useful for quick analysis, previews and lightweight exports.
✓Large video and audio files may need time to decode; smaller samples work faster in the browser.
✓When the result is a command, run it on a machine with the required media tools or model installed.
✓Review generated WAV, PNG, CSV and command outputs before using them in production workflows.
✓Fullscreen mode on tablets and desktops gives more room for waveforms, tables and video previews.
✓For final broadcast, podcast or advertising delivery, verify results with professional media tools too.
