An audio display system can include an audio input configured to receive a plurality of inputs corresponding different audio channels of a multi-channel audio signal. A phase calculator is configured to determine a relative phase between at least a given pair of the audio channels. An amplitude calculator is configured to determine an amplitude for at least the given pair of audio channels. A display generator is configured to generate an audio display. The audio display can include an amplitude element representing the amplitude determined for each audio channel in the given pair of the audio channels, the amplitude elements being spaced apart from each other to define a phase zone between the respective pair of amplitude elements. The audio display can also include a phase output plotted in the phase zone between the respective pair of amplitude elements, the phase output representing a phase relationship between the given pair of the audio channels.
