Channel Analysis settings panel
The Channel Analysis settings panel sets the thresholds used for hum
detection, channel swap detection and LFE bandwidth checking. It
controls all channel related measurements that are not level or loudness
related.
Hum Error if
Stable Tones at Sets the frequencies used for hum detection measure-
ments. Measurements are made at the fundamental frequency
and two harmonics.
Exceed Sets the level at which a HUM error will be generated. This may
be set in 5 dB increments from −50 to −85 dBFS.
With Tolerance Sets the maximum level variation a signal may have
before it is considered program and not hum. The choices are
±2 and ±4 dB.
For Longer Than Sets the duration that a signal must exceed the speci-
fied limits to generate a HUM error. The choices are 4, 8, 15 or
30 seconds.
LFE Channel Error If
Bandwidth Exceeds Sets the LFE bandwidth above which an LFE BW
error will be generated. The choices range from 80 to 250 Hz.
For Longer Than Sets the duration that a signal must exceed the speci-
fied bandwidth to generate an LFE BW error. The choices are 1,
3, 10 or 30 seconds.
Front and Surround or Back Swapped If
Front is Softer for Longer Than Sets duration that the surround or back
channels must exceed the front channels to generate a Front/
Surround Swap or Front/Back Swap error. The choices are 1, 3,
10 or 30 seconds.
