Patent ID: 7930171

Claim:
In an audio decoder, a method comprising: receiving, at the audio decoder, encoded information in a bit stream for audio in multiple channels, wherein the encoded information comprises: first encoded information encoded directly using coding processes that include a windowed overlapped transform, a selective multi-channel transform, scalar quantization and entropy encoding; and second encoded information encoded parametrically according to a parametric compression mode that accounts for audibility of distortion according to an auditory model, wherein the second encoded information includes a set of parameters that represent plural weight factors; with the audio decoder, decoding the first encoded information; with the audio decoder, decoding the second encoded information according to a parametric decompression mode, wherein the parametric decompression mode includes inverse quantizing the set of parameters that represent the plural weight factors, and wherein the parametric decompression mode further includes: computing linear prediction coefficients, wherein the linear prediction coefficients modify results of the decoding the first encoded information; with the audio decoder, reconstructing the audio using results of the decoding first encoded information and results of the decoding the second encoded information; and from the audio decoder, outputting the reconstructed audio.
