About the Lissajous measurement
In facilities for sound recording (such as broadcasting studios), the distance between a microphone and a sound source is automatically measured from the phase difference. The Lissajous waveform helps you obtain the optimal positioning of a dynamic microphone or a condenser microphone.
▌What is a phase difference?
A slight difference between two sound waves is |
|
|
|
|

called a phase difference. The sound is equally |

is directly in front of the sound source. However, |

the left and right channels if the sound source is |

slightly off either to the left side or right side of the microphone. |
