Audio Dynamic Range Meter
Watch the live spread between the loudest and quietest passages your microphone captures, in dB — the macro dynamics of a performance, room or recording.
ℹ Relative dBFS, not a mastering "DR/DR14" figure. This is the range of levels captured over time (loudest RMS minus quietest RMS above the noise gate). It includes room noise and depends on your uncalibrated mic — it is not the album DR rating or a calibrated spec. Nothing is recorded or uploaded.
Microphone
Dynamic range
Quietest is the lowest level above a −55 dBFS noise gate, so silence between sounds isn’t counted — in a noisy room the quietest may sit near that gate.
What This Measures
Dynamic range here is the gap between the loudest and quietest moments captured since you pressed Start. The meter smooths the microphone’s RMS level, tracks the maximum (loudest passage) and the minimum above a noise gate (quietest real passage, so dead silence doesn’t count), and shows the difference in dB. A whispered-to-shouted voice might span 30–40 dB; a steady tone barely moves.
It’s a great way to compare how dynamic two sources or rooms are, or to see how much a compressor squashes the range. But it’s in relative dBFS from an uncalibrated mic that also hears the room, so the absolute numbers aren’t a spec.
Why it isn’t a "DR rating"
Album "DR" values (like the DR meter / DR14 used in mastering) are computed from the audio file with a defined algorithm (peak vs RMS statistics per channel). This tool measures a live microphone’s level spread over time, which includes your room’s noise floor and the mic’s response — useful and intuitive, but a different thing from a file-based DR number.
