AM-Munition appears inconvenient and complex compared to other traditional dynamics
tools at first. However, with its combination of available steps, modes, and parameters, the
plug-in offers creative flexibility and provides a powerful tool in the hands of ambitious
sound engineers.
Overview of AM-Munition
AM-Munition is composed of the following sections:
Mode: The basic functionality of the plug-in is specified here. The normal mode is "stereo",
meaning the input signal is entered on 2 channels (left and right) to the sidechain and
thereby to the control circuit. In M/S mode, however, encoding the stereo signal will be
carried out in parts as "center" (left and right) and "side" (left-right, differential signal). After
this, both parts are sent to the sidechain. The functionality of M/S mode is exceptionally
well suited to compression of material from the pop and dance genres, where bass
sources are commonly positioned in the center of the stereo field. Normal compression in
stereo mode will always produce modulation or "pumping", since the bass drum or the
bass line reduces the total volume with its own energy. However, the division of the signal
into center and side information merely makes a stronger modulation in a different range of
the stereo field more noticeable.
OPTICAL COMPRESSOR: The heart of AM-Munition is made up of two compressor units
which are indicated by "1" and "2". Depending on the selected mode, you can edit the left
and right or the center and side signals. The compressors are based upon a very detail-
oriented modeling of an optoelectrical circuit. The principle in this case is very simple: the
input signal (Side Chain) is used to control a light source. The simulated light hits a photo
resistor (LDR, light dependent resistor), which produces changes in resistance depending
upon changes in brightness. These in turn directly affect the input resistance of the
compressor switching. One could say that the signal source is its own volume
potentiometer. In this case, the important factors are system capacity (light source, its
controls, and the applied photo resistance) and memory effects.Amazingly, circuits based
