Statistical properties of high quality stereo signals in the time domain

The bit rate used for high quality digital signal is 16 bit at a sampling frequency of 44.1 kHz (compact disc). Reducing the bit rate for stereo signals requires knowledge of the statistics. Probability densities and joint probability densities provide parameters for individual samples. Short time energies and correlation coefficients express similarities and linear relationship of blocks of samples. The original channels of stereo signal are compared to the signals generated from half of the sum and half of the difference of the original signals. Measurements for coloured (pink) noise are added to provide relations for the results of stereo signals.
