Abstract

An apparatus, method and computer program for generating a wideband signal using a lowband input signal includes a processor for performing a guided bandwidth extension operation using transmitted parameters and a blind bandwidth extension operation only using derived parameters rather than transmitted parameters. To this end, the processor includes a parameter generator for generating the parameters for the blind bandwidth extension operation.
