Abstract
A method for processing a multichannel audio signal includes: obtaining at least one group of signals associated with a pair of channels comprising a left side signal, a left central signal, a right central signal and a right side signal determined from the left input signal and the right input signal; and performing differentiated sound stage filtering for the central signals on the one hand, and the side signals of each group of signals on the other hand, the differentiated sound stage filtering including the application, for each group of signals, of the central sound stage filter to the left central signal and to the right central signal of said group of signals.
Claims10
A method for processing a multichannel audio signal comprising at least one pair of input signals comprising a right input signal and a left input signal for reproducing sounds via at least one pair of channels comprising a right channel and a left channel, the processing method comprising:
- obtaining, from said input signals, at least one group of signals, each group of signals being associated with a pair of channels, each group of signals comprising a left side signal, a left central signal, a right central signal and a right side signal determined from the left input signal and the right input signal;
- and
- performing differentiated sound stage filtering for the central signals on the one hand, and the side signals of each group of signals on the other hand, the differentiated sound stage filtering comprising the application, for each group of signals, of a central sound stage filter to the left central signal and to the right central signal of said group of signals.
