Method of reducing un-correlated noise in an audio processing device

摘要

An audio processing device comprises a multitude of electric input signals, each electric input signal being provided in a digitized form, and a control unit receiving said digitized electric input signals and providing a resulting enhanced signal. The control unit is configured to determine the resulting enhanced signal from said digitized electric input signals, or signals derived therefrom, according to a predefined scheme.

1. An audio processing device, comprising:
a multitude of electric input signals, each electric input signal being provided in a digitized form, and further in a time-frequency representation comprising a number of frequency bands k and a number of time instances m, a control unit receiving said digitized electric input signals and providing a resulting signal, wherein the control unit is configured to determine the resulting signal from said digitized electric input signals, or signals derived therefrom, according to a predefined scheme, wherein the predefined scheme comprises that the contents of a given time-frequency bin (k,m) of the resulting signal is determined from the content of the corresponding time-frequency bin (k,m) of the electric input signal, or a signal derived therefrom, comprising the least energy among said multitude of electric input signals.
