Multi-channel audio display

A display system, comprising:

• at least one input configured to receive a plurality of different signals;
• a phase calculator configured to determine a phase relationship between at least one selected pair of the plurality of different signals;
• a display generator configured to generate a display, the display comprising:
• a display element for each of the plurality of different signals, each of the display elements being spaced apart from each other to define a phase zone between a given pair of the display elements;
• and
• a phase output plotted in the phase zone between the given pair of display elements, the phase output being plotted as a function of time for a sweep period to represent the phase relationship between respective signals represented by the given pair of display elements over the sweep period.

A display system, comprising:

• an audio input configured to receive a plurality of inputs corresponding to different audio channels of surround sound audio;
• a phase calculator configured to determine a phase difference between respective pairs of the audio channels;
• an amplitude calculator configured to determine an amplitude level for each of the inputs;
• a display generator configured to generate an audio display, the audio display comprising:
• an amplitude element for each of the audio channels representing the amplitude level determined for each of the audio channels, each of the amplitude elements being arranged according to an expected arrangement of surround sound speakers for the audio channels, a phase zone extending between each of the respective pairs of the audio channels;
• and
• a phase output plotted in the phase zone between at least one given pair of amplitude elements, the phase output being plotted as a function of time for a sweep period to represent the phase difference between respective audio channels represented by the at least one given pair of amplitude elements over the sweep period.
