Abstract: A conversion method comprises the following steps: for each of the signals (bE(t)) of a first set, determining values (α(f)) respectively associated with frequency bands; for each frequency band, converting the values (α(f)) associated with the relevant frequency band into at least one value representative of a virtual sound source oriented along the spatial direction associated with a data item stored for the relevant temporal frequency band; for each temporal frequency band, determining, on the basis of an above-mentioned representative value, a plurality of values (γ(f)) associated with the different signals (bS(t)) of the second set, respectively; constructing each signal (bS(t)) of the second set on the basis of the values (γ(f)) associated with this signal of the second set.
