Abstract (en)
[origin: WO2015055946A1] The invention relates to a sound spatialisation, with the application of at least one transfer function with reverberation to at least one sound signal. This application amounts to multiplying, in the spectral range, spectral components of the sound signal by the spectral components of a filter corresponding to the transfer function, each spectral component of the filter having a temporal evolution in a time-frequency representation. In particular, the spectral components of the filter are especially ignored, for the above-mentioned multiplications of components, beyond a threshold frequency (Fc d(l), Fc g(l), Fcd(2), Fc g(2)) and after at least a given instant (m=l, m=2) in said time-frequency representation.
