ABSTRACT:
Apparatus for analyzing audio signals from a stereo pair of audio channels, comprises: means for detecting the magnitudes of the audio signals of the two audio channels; first detector for detecting a degree of phase correlation between the audio signals of the two audio channels; and second detector for generating an indicator color for display in respect of the audio channels at a time of test, the indicator color having a hue, intensity and/or saturation dependent on at least the relative magnitudes of and the degree of phase correlation between the audio signals of the two audio channels at the time of test.
