Level over time

RMS · 10.0 ms · 113 points

Active threshold -60.0 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 0.00 0.28 0.56 0.84 1.12 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.
