Abstract:
1. A method for processing an audio signal, comprising: receiving, by an audio processing apparatus, an audio signal including a first data of a first block encoded with a rectangular coding scheme and a second data of a second block encoded with a non-rectangular coding scheme; generating an output signal for the first block using the first data of the first block based on the rectangular coding scheme; receiving a compensation signal corresponding to the second block; obtaining a prediction of an aliasing part by applying a window of the second block to the output signal for the first block; and obtaining a reconstructed signal for the second block based on the second data, the compensation signal and the prediction of the aliasing part, wherein, when the first data is encoded with a LPD (Linear Prediction Domain) coding scheme and the window of the second block belongs to a transition window class, the window of the second block has an ascending line with a first slope, wherein the first slope is gentler than a second slope.
