Abstract
A method for processing a monophonic signal in a 3D audio decoder, including processing binauralizing decoded signals intended to be delivered spatially by a headset. The method is such that, on detection, in a datastream representative of the monophonic signal, of an indication of non-binauralization processing, which indication is associated with spatial delivery position information, the decoded monophonic signal is directed to a stereophonic rendering engine, which takes into account the position information to construct two delivery channels that are directly processed via a direct mixing that sums these two channels with a binauralized signal output from the binauralization processing, in order to be delivered via the headset. A decoder device that implements the processing method is also provided.
