Level over time

RMS · 10.0 ms · 89 points

Active threshold -46.0 dBFS
Short-window RMS level over time Each point is the channel-combined RMS of a non-overlapping frame. Values below −80 dBFS are pinned to the chart floor for display; the canonical JSON retains measured values, and digital silence remains null. 0 -20 -40 -60 -80 0.000 0.222 0.444 0.666 0.888 RMS (dBFS) Time (seconds)

Each point is the channel-combined RMS of a non-overlapping frame. Values below −80 dBFS are pinned to the chart floor for display; the canonical JSON retains measured values, and digital silence remains null.
