Graphically displaying stereo phase information

A computer program product, encoded on a computer-readable medium, operable to cause data processing apparatus to perform operations comprising:

• receiving audio data;
• separating the audio data into a plurality of samples;
• calculating stereo phase data for each sample of the plurality of samples, where calculating the stereo phase data includes calculating a phase angle and magnitude for each sample and combining the stereo phase data for the plurality of samples for each calculated phase angle;
• and
• displaying the calculated stereo phase data, where displaying the calculated stereo phase data includes displaying the combined stereo phase data for each calculated phase angle the displaying including plotting points using a histogram count for each phase angle as a function of a number and magnitude of samples at each calculated phase angle.
