Coding and decoding audio signal

An apparatus for generating a decoded audio signal divided into a plurality of frames or subframes according to ACELP, comprising:

• a coded signal reader configured to read at least, from a coded signal, coded information on prediction coefficients and coded information on at least one pulse;
• a signal processor configured to generate the decoded audio signal from at least a decoded version of the prediction coefficients and a decoded pulse combination, or the processed version thereof, wherein the decoded audio signal is generated at a first sampling, the first sampling implying, in one frame or subframe, a first plurality of sample positions having a first number of sample positions;
• wherein the apparatus is configured to derive the decoded pulse combination from the coded information on the at least one pulse and a second-sampling codebook, wherein the at least one second-sampling codebook comprises a set of pulse combinations defined at a second sampling, the second sampling implying, in the frame or subframe, a second plurality of sample positions having a second number of sample positions, wherein the first sampling is different from the second sampling at least in that the first plurality of sample positions is different from the second plurality of sample positions,
• wherein the second number of sample positions is smaller than the first number of sample positions, wherein the at least one second-sampling codebook is or includes an innovative codebook.
