Abstract  Abstract

the movable stage or the silent period parameter of background noise estimation is updated continuously so that when the movable stage entering inactive phase immediately starts generating noise. According to another aspect it is very effective to use spectral domain in order to parameterize the background noise thereby obtaining a more real background noise synthesis and thereby result in a more transparent active phase not to inactive phase switching.

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.
