A goniometer is often included in analog audio equipment to display a Lissajous figure which shows the amount of stereo (that is, phase differences) in a dual-channel signal. It allows the sound technician to adjust for optimal stereo and determine the makeup of errors such as an inverted signal.
What does a goniometer show?
A goniometer is an instrument that measures the available range of motion at a joint. The art and science of measuring the joint ranges in each plane of the joint are called goniometry. ... The term goniometry is derived from two Greek words, gonia, meaning "angle" and metron, meaning "measurement".
What is audio correlation?
Audio Correlation Measurement Basics
In our case correlation means the similarity of two audio signals. These two signals can be: +100% correlated, i.e., both signals are identical (except that their levels may be completely different).
What is phase correlation audio?
Essentially, it displays the changing phase relationships between the left and right channels of a stereo signal, but in more simple terms, it can be thought of as indicating the state of a stereo signal's mono compatibility.
