B1 – The Junger Audio Dynamics Processor Principle
Look Ahead/Signal Delay
The digital implementation of the
Junger Multi-loop design also permits a very short
time delay (approx. 2ms) to be introduced in the audio signal path. It lets the gain
changing elements “look ahead” and determine the correction needed. This is applied
to the delayed signal just in time to control even the fastest transients. That is
particularly important for the limiter, which provides a precisely levelled output signal
absolutely free of overshoots (clipping).
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 waveform at
other frequencies (comb filter effect). Corresponding 2ms delay of direct signals
should therefore be carried out before mixing them with delayed processed signals.
Adaptive Dynamic Range Control
The proprietary algorithms in the Junger System also allow the automatic adjustment
of the attack and release times according to the evolution of the input signal over time.
This is called Adaptive Dynamic Range Control. By monitoring the waveform of the
incoming audio, the System can set relatively long attack times during steady-state
signal conditions but very short attack times when there are impulsive transients.
The Best Performance
The dynamic range processor principles developed by Junger Audio make it possible
to realize dynamics processors (compressor, limiter, expander) with very high audio
quality, without signal coloration, pumping or breathing, and without distortion and
modulation products.
In short, they offer the best possible performance – inaudible dynamics control.
