StereoExpander
The StereoExpander plug-in narrows or enlarges the stereo width of an
existing stereo signal. There is only one parameter, the horizontal stereo
effect slider. Setting this to a value of -100% produces two equal output
channels (the original stereo image is lost). Values between -99 and -1
correspond to a narrower stereo image. A value of 0 corresponds to the
original signal, while values between 1 and 100 enlarge the stereo image.
Tools One
Tools One is an extremely useful “effect” for various applications.
The level faders allow you to adjust the level of the left and right channel
respectively. You can [Shift]-drag to make detailed settings. [Ctrl]-clicking
a fader resets it to 0 dB (no level adjustment). Normally, adjusting one
fader automatically moves the other as well, but you can make separate
adjustments for the channels by pressing [Alt] and dragging.
The two Phase switches let you invert the phase of the left or right chan-
nel (or both).
The Algorithm buttons let you adjust the stereo sound image. When none
of the buttons are activated, the stereo image will be preserved as is. MS
process mode can be used in one of two ways:
• To transform an incoming “regular” stereo signal so that it resembles a signal re-
corded according to the M-S (middle/side) principle. This technique is often used
in broadcasting to record the direct signal source (usually a voice) using one micro-
phone, and the ambience using a second microphone positioned at a 90° angle.
• To transform an incoming MS signal into a “regular” stereo signal (to simulate an
“XY” recording technique, where neither microphone is placed directly in front of
the signal source).
Channel Swap, finally, means that the left channel is assigned to the right
side and the right channel to the left side.
Volume L The output level of the left channel delay.
Volume R The output level of the right channel delay.
