Patent ID: 8401865

Claim:
A method, comprising: extracting a coded parameter set from an encoded speech/audio stream, wherein said encoded speech/audio stream is distributed to a sequence of packets; and generating a time scaled encoded audio/speech stream in the parameter coded domain using said extracted coded parameter set, wherein said extracted coded parameter set comprises at least one coded parameter, and wherein said at least one coded parameter is associated with at least one point in time, and wherein the method further comprises: determining at least one time scaled coded parameter based on said at least one coded parameter and on a time shift value, wherein this determining is performed in a coded domain; wherein said at least one coded parameter represents at least one time-domain coded coefficient associated with at least one parameter type, and wherein at least one of said at least one coded parameters is associated with one single parameter type of said at least one parameter types, and wherein at least one of said at least one time scaled coded parameters associated with said one single parameter type is determined by means of at least one out of the following functions: interpolation based on at least two of said at least one coded parameters associated with said one single parameter type, and extrapolation based on at least one of said at least one coded parameters associated with said one single parameter type; and wherein said at least one parameter type is at least one out of: Linear Predictive Coding (LPC) filter parameter type; pitch lag parameter type; fixed codebook gain parameter type; and adaptive codebook gain parameter type.
