Abstract:
1. A method of decoding an audio signal, the method comprising: receiving the audio signal including a prediction residual of a block of digital audio data and coded coefficient values; obtaining table index information from the digital audio data, the table index information identifying a table from a plurality of tables to select; reconstructing a set of prediction coefficient values from the coded-coefficient values, the reconstruction including, converting the prediction coefficient values into linear predictive coding (LPC) coefficients: predicting current data samples in the block based on the LPC coefficients; second entropy decoding the prediction residual using second entropy codes, the second entropy codes representing Rice codes or Block Gilbert Moore Code (BGMC) codes; and obtaining decoded data samples based on the predicted current data samples and the prediction residual, wherein the calculating a set of prediction coefficient values step adds the offset values to the coded-coefficient values.
