摘要：
An apparatus for generating an error concealment signal, comprises: an LPC (linear prediction coding) representation generator (100) for generating a first replacement LPC representation and a different second replacement LPC representation; an LPC synthesizer (106) for filtering a first codebook information using the first replacement representation to obtain a first replacement signal and for filtering a different second codebook information using the second replacement LPC representation to obtain a second replacement signal; and a replacement signal combiner (110) for combining the first replacement signal and the second replacement signal to obtain the error concealment signal (111).
