Abstract  Abstract

Systems methods and DEVICES FOR suppression OF BURST IN BANDWIDTH. In one embodiment one for suppressing a burst of high bandwidth includes one first a burst detector configured to detect bursts in groups for the speech signal of low bandwidth and second groups of burst detector configured to detect bursts in groups for the speech signal of corresponding high bandwidth. The signals of the speech low bandwidth and high bandwidth podeúi be regions of freqúências different (possibly overlapping if) of one signal of the broadband speech. The suppressing a burst of high bandwidth also includes one calculator to the signal of the control atenuaçào configured for calculating one signal of the attenuation control of according with a difference between outputs of the first and second detectors of burst. One element of the gain control is configured for applying the signal of the attenuation control signal of the speech of high bandwidth. In one example the signal control of the attenuation indicates a attenuation when a burst is found in the speech signal of high bandwidth but which is absent of a corresponding region in time the signal of speech the low band.
