Abstract  Abstract

Continuously updating the movable stage or non-silent period parameter background noise estimation immediately when the start time for generating noise entering into an inactive phase rear on the movable stage. According to one other aspect it is very effective to use frequency domain parameter to the background noise so as to obtain more real of background noise and thereby resulting in more transparent of the movable stage to active phase.

A parametric background noise estimate is continuously updated during an active or non-silence phase so that the noise generation may immediately be started with upon the entrance of an inactive phase following the active phase. In accordance with another aspect a spectral domain is very efficiently used in order to parameterize the background noise thereby yielding a background noise synthesis which is more realistic and thus leads to a more transparent active to inactive phase switching.
