Goniometer
The Goniometer helps you to determine the coherence of the stereo image. Using the
Goniometer, you can see phase problems as trace cancelations along the center line
(M=mid/mono). Goniometers developed when early two channel oscilloscopes first
appeared. Users would connect the left and right stereo channels to the X and Y inputs
while rotating the display by 45 degrees, resulting in a useful visualization of the signal’s
stereo phase.
MultiMeter with Goniometer active
The signal trace slowly fades to black, imitating the glow of the tubes found in older
Goniometers, and at the same time enhancing readability.
Clicking the Goniometer button turns on the Goniometer and turns off the Spectrum
Analyzer. You can use the Auto Gain display parameter in order to obtain a higher readout
on low-level passages. Auto Gain allows the display to automatically compensate for low
input levels. You can set the amount of compensation with the Auto Gain parameter, or
set Auto Gain by dragging directly in the display area of the Goniometer.
Note: Auto Gain is a display parameter only and increases the display for better readability.
The actual audio levels are not touched by this parameter.
Miscellaneous Effects
Miscellaneous effects don’t fall into any of the other categories. They include denoising
effects, pitch shifting effects, stereo enhancers, bass enhancers, and effects used to
transform the sound of vocals. Each effect gives you a different way to modify the audio,
and includes a unique set of parameters.
