Claim 24:
25. A non-transitory digital storage medium having stored thereon a computer program for performing, when running on a computer, a method of decoding an encoded audio signal comprising a first encoded audio signal portion and a second encoded audio signal portion to obtain a decoded audio signal, the method comprising:
first decoding the first encoded audio signal portion in a frequency domain to acquire a decoded time domain first audio signal portion;
second decoding the second encoded audio signal portion in the time domain to acquire a decoded time domain second audio signal portion having a low band and a high band; and
combining the decoded time domain first audio signal portion and the decoded time domain second audio signal portion to acquire the decoded audio signal,
wherein the first decoding comprises: decoding first spectral portions with a high spectral resolution and synthesizing second portions using a parametric representation of the second spectral portions and at least a decoded first spectral portion to acquire a decoded spectral representation, wherein the decoding generates the decoded spectral representation so that a first spectral portion is placed with respect to frequency between two second spectral portions; and converting the decoded spectral representation into a time domain to acquire a decoded time domain first audio signal portion.
