Abstract
Official abstract text for this publication.
An apparatus for processing an audio signal and method thereof are disclosed. The present invention includes receiving, by an audio processing apparatus, an audio signal including a first data of a first block encoded with rectangular coding scheme and a second data of a second block encoded with non-rectangular coding scheme; receiving a compensation signal corresponding to the second block; estimating a prediction of an aliasing part using the first data; and, obtaining a reconstructed signal for the second block based on the second data, the compensation signal and the prediction of aliasing part.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for processing an audio signal, comprising: receiving, by an audio processing apparatus, coding identification information indicating whether to apply a first coding scheme being based on linear-prediction domain or a second coding scheme being based on frequency domain to a current frame; when the coding identification information indicates that the second coding scheme being based on frequency domain is applied to the current frame, receiving wi…
