The transient processor immediately reduces or raises the level of a new program part
so that level jumps over 10…12dB are eliminated.
A compressor/limiter combination of a known dynamics processor by Junger Audio is
always controlling the audio level in relation to the limiter threshold. In result no
headroom is more existing and the signal is developed to reach a 100% output level.
This characteristic is useful to reach maximum levelling for audio disk mastering as
well as to reach 100% modulation for FM transmitters.
In compare to that Level Magic™ is serving two different levels – operating level and
peak level. Between operating and peak level we will find the so called “headroom” for
peaks that are still coming with the audio signal, even if this is level controlled related
to the operating level. Level Magic™ is a unique algorithm to make automated audio
level control possible. It is a combination of an adaptive AGC (automated gain control)
with a transient processor and a brickwall limiter. The combination of an AGC circuit
with a transient processor is the key to get a satisfying output level control for any kind
of input level changes.

The picture is showing a theoretical level change
of +5dB and –5dB around operating level.
What makes the Level Magic different from previous dynamics processors?
