摘要： The method of playing back a multichannel audio signal via a playback device comprises a plurality of loudspeakers arranged at fixed locations of the device and define a spatial window for sound playback relative to a reference spatial position. The method comprises for at least one sound object extracted from the signal, estimating a diffuse or localized nature of the object and estimating its position relative to the window. The audio signal is played back via the loudspeakers of the device during which playback treatment is applied to each sound object for playing back via at least one loudspeaker of the device, which treatment depends on the diffuse or localized nature of the object and on its position relative to the window, and includes creating at least one virtual source outside the window from loudspeakers of the device when the object is estimated as being diffuse or positioned outside the window.
