Claims11
A device for processing multi-channel audio signals that include at least a left channel, a right channel, and a center channel, the device comprising:
- a center extraction unit adapted for extracting a center signal from the left channel and the right channel, wherein a left remainder signal and a right remainder signal remain;
- a first summation unit for adding the extracted center signal to the center channel of the multi-channel audio signal to obtain an enhanced center channel;
- a second summation unit adapted for adding the enhanced center channel to the right remainder signal to obtain an enhanced right channel;
- a third summation unit adapted for adding the enhanced center channel to the left remainder signal to obtain an enhanced left channel;
- and
- outputs for providing the enhanced left channel, the enhanced right channel, and enhanced center channel.
A method for processing multi-channel audio signals, the multi-channel audio signals comprising at least a left channel, a right channel, and a center channel, the method comprising:
- performing a center extraction for the left channel and right channel to obtain an extracted center signal, wherein a left remainder signal and a right remainder signal remain;
- adding the extracted center signal to the center channel of the multi-channel audio signal to obtain an enhanced center channel;
- adding the enhanced center channel to the left remainder signal to obtain an enhanced left channel;
- adding the enhanced center channel to the right remainder signal to obtain an enhanced right channel;
- and
- providing the enhanced left channel, the enhanced right channel, and the enhanced center channel for output to respective speakers.
