Conversion and Rendering : Level Magic™, from Jünger Audio Page 99
The settings available here offer fine-grained control over the Level Magic process.
Level Magic
EBU R128
ITU.1770 (ATSC)
Surround Link Mode Determines which channels are linked for surround processing. The drop-down list offers
the choice of
ALL , LIVE , MOVIE or QUAD . Use ALL for loudness control. (LFE is omitted
from the linkage in each case.)
All the rest of the variables can be set independently for Surround and Stereo
Input Gain The drop-down lists offer a range of values from -20dB to 20dB in 1dB increments.
Leveler
Zero Zone Above Sets the upper boundary for AGC unity gain. Input loudness = Output loudness from this
point downwards if the input loudness decreases. The drop-down lists offer a range of
values from 0dB to 6dB in 1dB increments. Normal value is 0dB
Target Level Sets the target loudness level. The drop-down lists offer a range of values from -50dB to
0dB in 1dB increments. Set according to the required standard. E.g. EBU R128 is -23LUFS
Zero Zone Below Sets the lower boundary for AGC unity gain. Input loudness = Output loudness from this
point upwards if the input loudness increases. The drop-down lists offers a range of val-
ues from 0dB to 6dB in 1dB increments. Normal value is 0dB
Release Time Sets the time it takes for gain to reach maximum. The drop-down lists offer a range of val-
ues between 10s and 2h. 40s is a good starting point with larger values for looser control,
smaller for tighter control.
Max Gain Sets the maximum gain which the Leveler will apply. (Attenuation applied may be
higher.) The drop-down lists offers a range of values from 0dB to 40dB in 2dB increments.
10dB is “normal”, 14dB for more control, 6dB for less control.
Freeze Level Stop value for gain changeof the Leveler and Transient Processor to prevent unwanted
increase in noise. (The process freezes.) The drop-down lists offers a range of values from
-60dBFS to -20dBFS in 5dB increments. -40dB is average, -50dB for tighter control and -
35dB for looser control.
Transient Processor
Response Determines the “grip” of the Transient Processor. The drop-down lists offer the choice of
soft, mid or hard.
Max Gain Sets the maximum gain which the Transient Processor will apply. (Attenuation applied
may be higher.) The drop-down lists offers a range of values from 0dB to 15dB in 1dB
increments.
Limiter
Max Peak Sets the maximum peak output level. The drop-down lists offers a range of values from -
20dB to 0dB in 1dB increments.
Processing Determines the processing program which will be used by the Limiter. The drop-down
lists offer the choice of uni, live, pop or classic.
