Compressor Section
Two completely different compressors work in AM-Track, each with their own independent
control and sound methods.
You may be wondering why we mention sound when talking about a compressor, since
compressors merely relate to control actions. This isn't as simple as the idea of "making
loud quiet".
Various designs, algorithms, and topologies for solving the actual problem (dynamic
reduction), which all have their own unique character, have come from the history of analog
and digital signal processing. For example, pre-filtering in the detector circle and the type of
detection have a large influence on the audio results. Plenty of hardware compressors have
the same established VCAs (voltage controlled amplifier), but they all sound different and
influence a signal, an entire production (or even a genre) with their "signature sound". We
intend to provide you with acoustic variation via these dynamic tools in the digital world.
The two operating modes of the AM-Track may be selected using the switch "vca/vintage":
VCA Mode
In VCA mode, the parameter selection and the circuitry design
correspond to a modern compressor with a VCA element as the
control circuit and a forward automatic gain control in the detector
section ("feed-forward design", i.e. the controlling signal for level
reduction is taken from the input signal).
The typical basic sound for this category is accurate, largely neutral and, in relation to the
adjustable parameters, easily predictable.
In VCA mode, the control signal is accessed at the input where it firstly executes a
controllable low-cut (which may be set up via "detector hp freq" in "Expert" mode). The
filter makes sure that deep-frequency signals have less influence on the adjustment
settings; this is a popular trick for more power, e.g., when using drums in a sub-group.
