摘要： It is inter alia disclosed to receive a set of encoded audio parameters for an audio frame, wherein the set comprises indices representing at least two quantized line spectral frequency coefficients, wherein the audio frame when decoded comprises audio samples digitally sampled at a sampling frequency, wherein the sampling frequency is one of a plurality of sampling frequencies for an audio decoder;to convert the indices to the at least two quantized line spectral frequency coefficients; and to determine the sampling frequency for the audio frame by checking the value of a highest order quantized line spectral frequency coefficient of the at least two quantized line spectral frequency coefficients.

摘要： It is inter alia disclosed to determine, for each set of basis code vectors of a plurality of sets of basis code vectors, a potential basis code vector for encoding an input vector, wherein each set of basis code vectors is associated with at least one scale representative of a plurality of scale representatives, and to determine a code vector for encoding the input vector from a subset of code vectors, said subset of code vectors comprising, for each determined potential basis code vector and each scale representative associated with the set of basis code vectors of the respective potential basis code vector, a code vector based on the respective potential basis code vector scaled by the respective scale representative.
