APPARATUS AND METHOD FOR PRODUCTION OF A SURROUNDING-AREA SIGNAL

摘要

In order to produce a surrounding-area signal which is suitable for transmission via loudspeakers which do not have their own loudspeaker signal, that is to say for example for surround channels, a transient detector (11) is provided in order to detect a transient time period. A synthesis signal generator (12) produces a synthesis signal which on the one hand satisfies the transient condition and on the other hand satisfies the continuity condition for the synthesis signal. A signal substitutor (14) then replaces a section of the investigation signal by the synthesis signal, in order to obtain a surrounding-area signal for the surround channels.
