METHOD AND APPARATUS FOR PROVIDING AN ACOUSTIC SIGNAL WITH EXTENDED BANDWIDTH

摘要

PROBLEM TO BE SOLVED: To provide an acoustic signal with an extended bandwidth. SOLUTION: The invention is directed to a method and an apparatus for providing an acoustic signal with extended bandwidth, comprising providing an upper extension signal for extending a received acoustic signal at the upper frequencies, wherein providing the upper extension signal comprises shifting the received acoustic signal, at least higher than a predetermined lower frequency value and/or lower than a predetermined upper frequency value by a predetermined shifting frequency value to obtain a shifted signal.
