Abstract
A method of sound spatialization, in which at least one filtering process, including summation, is applied, to at least two input signals, the filtering process comprising: the application of at least one first room effect transfer function, the first transfer function being specific to each input signal, and the application of at least one second room effect transfer function, the second transfer function being common to all input signals. The method is such that it comprises a step of weighting at least one input signal with a weighting factor, said weighting factor being specific to each of the input signals.
