Abstract
The invention relates to a method of processing an input signal into a phantomized signal, including adding at least one attenuated delayed signal to the input signal, the phantomized signal having at least one delayed attenuated signal and the input signal. A phantomized signal according to the invention offers a new and impressive integration of a center channel signal of a multi channel audio system into the complete audio image provided by the system.
Claims17
Method of processing a center input signal (59;
- CC) into a phantomized signal (58), said method comprising the step of adding at least one attenuated delayed signal to said input signal (59;
- CC).
Phantomizer for processing a signal into a phantomized signal for reproduction at the center channel of a multi-channel rendering system, said phantomizer comprising at least one signal input (59) connected to comb-filtering means (52), said comb-filtering means feeding at least one signal output (58).
Inverse phantomizer for processing of at least two panned signals into de-phantomized signals for reproduction in a multi-channel rendering system, said phantomizer comprising two signal inputs (69L, 69R) each connected to inverse comb-filtering means (62L, 62R), each inverse comb-filtering means (62L, 62R) feeding at least one one signal output (68L, 68R).
Method of phantomizing a center channel signal of a multi-channel reproduction system, said signal being manipulated in such a way that the timbre of the signal, when reproduced in the center channel loudspeaker of a multi channel reproduction system, may be perceived by a listener as an audio signal which has been established in a multi-channel reproduction system having no center channel, such as stereo.
Method of phantomizing a center channel signal of a multi-channel reproduction system, said signal being manipulated in such a way that the timbre of the signal, when reproduced in the center channel loudspeaker of a multi channel reproduction system, may be perceived by a listener as an audio-signal reproduced by at least two neighboring channels when established in a multi-channel reproduction system.
