6.2
The audio signal delay through the dynamics
processor is approx. 2ms @ 44.1/48kHz or
1ms @ 88.2/96kHz due
audio signal using internal memory. A small
delay is deliberately introduced to the audio
signal in order to allow limiter and compressor
algorithms which can
signal before changing it. That is the signal
curve can be changed before maximum level is
reached. (see chapter 2.3.5).
6.3
The basic Multi-Loop principle of Jünger Audio
dynamics processors operates with adaption of
dynamic range control parameters to the
incoming audio signal. That means permanently
analysis and calculation of attack times, release
times , thresholds and interaction parameters of
several frequency linear control circuits.

signals.
When mixing together a delayed signal and a
direct signal there may be cancellation of the
signal waveform at some frequencies and re-
inforcement of the
frequencies (comb filter effect). Corresponding
2ms or 1ms delay of direct signals should
therefore be carried out before mixing them
with delayed processed signals.
For some of the control parameters it is
possible to define a limited range of time
constant values which is 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 programme material.
