Abstract (en)
[origin: WO2015011078A1] The invention essentially relates to a method for suppressing the late reverberation of an audible signal, characterised in that it comprises the following steps: calculation (907) of a plurality of prediction vectors; creation (908) of a plurality of observation vectors from the module of the complex time-frequency transform of an input signal; construction (909) of a plurality of synthesis dictionaries from the plurality of observation vectors; estimation (910) of a late reverberation spectrum from the plurality of synthesis dictionaries and the plurality of prediction vectors; and filtering (912) of the plurality of observation vectors in order to eliminate the late reverberation spectrum and to produce a dereverberated signal.
