SWEET SPOT MANIPULATION FOR A MULTI-CHANNEL SIGNAL
摘要
<p>An apparatus, such as a decoder is arranged to modify the sweet-spot of a spatial M-channel audio signal by modifying spatial parameters. Specifically, a receiver (201) receives an N-channel audio signal where N<M. The M-channel signal may specifically be an MPEG Surround sound signal and the N-channel signal may be a stereo signal. A parameter unit (203) determines spatial parameters relating the N-channel audio signal to the spatial M-channel audio signal and a modifying unit (207) modifies the sweet- spot of the spatial M-channel audio signal by modifying at least one of the spatial parameters. A generating unit (205) then generates the spatial M-channel audio signal by up-mixing the N-channel audio signal using the at least one modified spatial parameter. An efficient and/or low complexity sweet-spot manipulation is achieved by an integration of sweet-spot manipulation and multi-channel generation.</p>
