ness
LMT
- Utilizes a specially tuned Input AGC plus Multiband Limiters and the Final Limiter to slowly
adjust the average program loudness to a given value and the multiband and final limiters will act until the AGC
catches up. This preset is appropriate for ingest or live applications but because the Multiband AGC is bypassed
it has less ability to manage spectral balance which is important for transmission.
•
PROTECTION LIMIT
- Bypasses all processing except for the final output limiter which is set only to prevent
overload.
NOTE: All presets (except
PROTECTION LIMIT)
were tuned to produce audio that will have an average dialog
loudness of
-24 dB/LKFS
as measured by a Dolby LM100.
For the other parameters in the Basic tab, refer to the Advanced Configuration section below.
6.5.3 Advanced Configuration – ALC PGM 1 & 2
We
STRONGLY
recommend starting with an ALC preset and modifying from there. Preset creation starting from
scratch is an incredibly time consuming process requiring large amounts of time and huge amounts of content
spanning all genres including music of every type, films of every type, television dramas and sitcoms of every type,
and talking-head programs of every type. Linear Acoustic has already done much of the heavy lifting, and provides
presets based on their own listening and feedback from customers over the past few years. Certain parameters such
as crossover frequencies and channel coupling are not adjustable and are hard-coded to the most appropriate values.
That being said, access to all adjustable parameters is provided. There are no factory adjustments hidden from users.
Be careful with this power as most all settings interact with each other, sometimes in ways that might not be
immediately audible.

processing core
The drawing above shows the general signal flow of the processing core to indicate what part of the chain is being
adjusted by each parameter. Note that this signal flow is also captured in the “Adjust Processing” menu, with the top
of the list being the input, and the bottom of the list being the output.
