AUDIO METER LEVELS
Figure: Audio Meter
The camera updates the Audio Meter 12 times per second with the maximum signal from the last 1/12 of a second period.
The range of the Audio Meter is –52 dBFS to 0 dBFS.
The lines and colors indicate danger of clipping, as described in the table below:
LINE
DBFS
DESCRIPTION
First line (far left border)
–52 dBFS
Audio is not clipping
Second line
–20 dBFS
Audio is not clipping
Third line
–12 dBFS
Audio close to clipping
Fourth line
–2 dBFS
Audio is clipping
Fifth line (far right border)
0 dBFS
Audio is clipping (if signal exceeds –1 dBFS, the whole bar is red)
NOTE: In the American broadcast and post production systems, –20 dBFS roughly corresponds to 0 VU and 4 dBu. In a digital
system, dBu is an approximation; the correct unit for digital audio levels is dBFS.
AUDIO DURING PLAYBACK
The camera plays all recorded channels during playback, and automatically unmutes any muted audio outputs.
