Claim 4:
5. A non-transitory digital storage medium having a computer program stored thereon to perform the method of decoding an encoded audio signal, comprising:
decoding a first encoded audio signal portion in a frequency domain to obtain a decoded spectral representation, the decoding comprising converting the decoded spectral representation into a time domain to acquire a decoded first audio signal portion, wherein the decoding the first encoded audio signal portion comprises reconstructing a first set of first spectral portions in a waveform—preserving manner to generate a spectrum having gaps, and filling the gaps in the spectrum with an Intelligent Gap Filling (IGF) technology comprising using a frequency regeneration applying parametric data and using reconstructed first spectral portions of the first set of first spectral portions;
decoding a second encoded audio signal portion in the time domain to acquire a decoded second audio signal portion;
calculating, from the decoded spectral representation of the first encoded audio signal portion, initialization data of the step of decoding the second encoded audio signal portion, so that the step of decoding the second encoded audio signal portion is initialized to decode the second encoded audio signal portion following in time the first encoded audio signal portion in the encoded audio signal; and
combining the decoded first audio signal portion and the decoded second audio signal portion to acquire a decoded audio signal,
when said computer program is run by a computer.
