Abstract:
1. In a decorrelator, a method of synthesizing a first and a second output signal from an input signal, the method comprising: applying the input signal to a filter of the decorrelator to generate a filtered signal; obtaining from an analysis circuit of the decorrelator a correlation parameter indicative of a desired correlation between the first and second output signals; obtaining from the analysis circuit of the decorrelator a level parameter indicative of a desired level difference between the first and second output signals; and applying the input signal and the filtered signal to a transformation circuit of the decorrelator and performing by a matrixing operation on the input signal and the filtered signal to transform the input signal and the filtered signal into the first and second output signals, where the matrixing operation employs the correlation parameter and the level parameter.
