Abstract:
1. An audio signal decoder configured to provide a decoded audio signal representation on the basis of an encoded audio signal representation comprising a sampling frequency information, an encoded time warp information and an encoded spectrum representation, the audio signal decoder comprising: a time warp calculator configured to map the encoded time warp information onto a decoded time warp information, wherein the time warp calculator is configured to adapt a mapping rule for mapping codewords of the encoded time warp information onto decoded time warp values describing the decoded time warp information in dependence on the sampling frequency information; and a warp decoder configured to provide the decoded audio signal representation on the basis of the encoded spectrum representation and in dependence on the decoded time warp information; wherein the audio signal decoder is implemented using a hardware apparatus, or using a computer, or using a combination of a hardware apparatus and a computer.
