Audio match This bar graph represents the degree to which there is a
match between the reference audio signal and the probed
audio signal.
• Green: good match (3-5 bars)
• Yellow: marginal match (2 bars)
• Red: poor match or no match (1 bar)
Lip-sync Current measurement (in milliseconds):
• if the signal match is not normal,
• if silence or low motion is detected on probed or
reference signal, or
• if updates to this measurement are interrupted
The precision of the lip-sync delay measurement is
+/ 1 msec. A positive value (+) indicates that audio is late
with respect to the video (lagging). A negative value (-)
indicates that the audio leads the video.
