Claim:
1. A method for sound spatialization, comprising the application of at least one transfer function with room effect to at least one sound signal, said application amounting to multiplying, in the spectral range, spectral components of the sound signal by the spectral components of a filter corresponding to said transfer function, each spectral component of the filter having a temporal variation in a time-frequency representation, wherein said spectral components of the filter are ignored, for said multiplications of components, beyond a threshold frequency and after at least a given instant in said time-frequency representation, and wherein, for an implementation by a sound spatialization module receiving a plurality of input signals and providing at least two output signals, in order to provide each output signal, a transfer function with room effect is applied to each input signal, each of said output signals being given by applying a formula of the type: O l ε[1; L] being the index relating to an input signal among said input signals, L being the number of input signals, and I(l) being an input signal among said input signals, A B W z the symbol “.” designating multiplication, the term “*[0; . . . ; f the term “*[0; . . . ; f
