Abstract: Method and system for use with multimedia signals that analyzes the signals into time-frequency frames over first and second time periods. Estimates of the noise and/or reverberation are derived from the frames. Gains are derived from the estimates and raised to a power to create modified gains. The modified gains are applied to the frame in the appropriate time periods. Modified multimedia signals are output after being processed by the modified gains.

Abstract: 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.
