Emulation
Unity Gain Mode [OFF / ON]
For applications like live
mixing or others where the
level must not be changed
but listening to the influence
of DRC is desired.
MD Generator overwrites [OFF / ON]
encoded Metadata If you want to see how different metadata will "sound" for already
encoded signals you may decode it and apply different ones to it.
Decoding and DRC
Custom Mode [0 … 0.5 … 1]
Boost Factor If you want to check out different DRC behaviour from the defined
profiles you may set the lover level boost factor here.
Custom Mode [0 … 0.5 … 1]
Cut Factor If you want to check out different DRC behaviour from the defined
profiles you may set the higher level cut factor here.
Here a simplified DRC
characteristic curve,
published by Dolby®:
Important Note! Dolby Digital and Digital plus encoded streams do not contain metadata for
DRC but pre-calculated gain words which may be applied to the decoded audio to decrease dynamic range
for home reproduction. That's why you will not get a display of such metadata from the Input if consumer
format streams are decoded. Similar applies to the professional metadata which is used to setup
consumer format encoders (e.g. filters) and which is not present in the metadata stream as well.
Status display of Decoder/Emulation / Encoder A / Encoder B / Metadata (soft LEDs)
Green * Dolby encoded stream at the input
* Metadata valid from the generator
Orange * Dolby E frame rate mismatch
* MD generator has entered the reversion mode
* Dolby E encoder has entered the reversion mode
Red * If the decoder receives corrupted (e.g. asynchronous)
or no metadata
* Internal error
Important Note! If no input metadata is available for PCM emulation and you tick a
checkbox, the generator enters the reversion mode as well.
