기술적인 설명
The analyser computes RMS and peak levels from the microphone signal. The reported dBFS value is relative to digital full scale, not sound pressure level (dB SPL).
Microphone gain, automatic gain control, and device processing vary widely. Results are useful for comparisons on the same device and in the same session, not as calibrated environmental noise measurements.
문제 해결
Noise floor stays at zero
Check that the microphone is connected, unmuted, and selected correctly. Some browsers apply aggressive noise suppression that removes quiet sounds.
Readings jump around
Fans, keyboards, traffic, and notifications create short peaks. Observe a longer period and compare averages.
Value is much lower than expected
dBFS is relative to the digital signal, not a calibrated room measurement.
Permission prompt does not appear
