Patent ID: 8484038

Claim:
An audio signal decoding device for providing a decoded representation of an audio content on the basis of an encoded representation of the audio content, the audio signal decoder comprising: a transform domain path configured to acquire a time domain representation of a portion of the audio content encoded in a transform domain mode on the basis of a first set of spectral coefficients, a representation of an aliasing-cancellation stimulus signal and a plurality of linear-prediction-domain parameters, wherein the transform domain path comprises a spectrum processor configured to apply a spectral shaping to the first set of spectral coefficients in dependence on at least a subset of the linear-prediction-domain parameters, to acquire a spectrally-shaped version of the first set of spectral coefficients, wherein the transform domain path comprises a first frequency-domain-to-time-domain converter configured to acquire a time-domain representation of the audio content on the basis of the spectrally-shaped version of the first set of spectral coefficients; wherein the transform domain path comprises an aliasing-cancellation stimulus filter configured to filter an aliasing-cancellation stimulus signal in dependence on at least a subset of the linear-prediction-domain parameters, to derive an aliasing-cancellation synthesis signal from the aliasing-cancellation stimulus signal; and wherein the transform domain path also comprises a combiner configured to combine the time-domain representation of the audio content with the aliasing-cancellation synthesis signal, or a post-processed version thereof, to acquire an aliasing-reduced time-domain signal; Wherein at least one of the spectrum processor, domain converter, aliasing cancellation stimulus filter, or combiner are executed by an apparatus.
