THE JUNGER AUDIO DYNAMICS
PROCESSING PRESETS
For some of the control parameter it is possible to define a limited range of time
constant values which are allowed for the adaptive dynamic range algorithms.
Inside this range the time constants can be varied by the adaptive processing.
Setting the range of time constant values may be sometimes useful, to get the best
signal processing performance regarding specific program material.
Parameter related to the transient response of the control circuit are important for
distortion-free processing. These time constants are always adaptive controlled
without remarkable limitation of parameter range. This is caused by the presence
of transient pulses in almost each kind of program material. The algorithm has to
guarantee best reaction for fast increasing level of transient signals anytime even if
classical music with slow dieing out characteristic is processed. In all cases the
attack time of the limiter for very short transients is zero.
Especially the release time of the control circuit has more influence to the increase
of loudness as any other parameter. The ranging of time constants in processing
time groups reflects this fact. The range for processing time shows influence on
release time parameter mostly.
The selection of the parameter PROCESS/PROGRAMM (limiter, compressor)
changes the range of time constant values as follows:
