The Audio Vector Scope was added in the 24.04 release.
The Audio Vector Scope provides an illustration of the phase relationship between two channels. A typical display for two stereo channels is shown below:
To show the phase relationship between different channels, choose the channels from the drop down boxes:
If the vector scope shows a vertical line without any horizontal separation between the points, that means the two channels are perfectly in phase. Typically caused by a mono signal that is split to left and right:
If the vector scope shows a horizontal line without any vertical separation between the points, that means the two channels are perfectly out of phase. This means one channel is an inverted version of the other channel. This can be caused by microphones that are wired incorrectly. The problem with such an audio signal is that if they are summed together (such as converting stereo to mono), the channels will cancel out and the result will be silence. The following figure shows the vector display for two channels that are inverted. It also shows the waveform display where you can see that the waveforms are the exact opposite.
