METHOD AND SYSTEM OF SIGNAL DECOMPOSITION USING EXTENDED TIME-FREQUENCY TRANSFORMATIONS

A system and method of decomposing a source signal comprising first and second sound signals, using an extended time-frequency transformation formed by combining a time frequency transformation of a first representation of the source signal with a time-frequency transformation of a second representation of the source signal. The source signal can comprise music, speech, video or other multimedia signals and the decomposition can be controlled by a single knob user interface.
