[ 11. A method for processing an audio signal including a first data of a first block encoded with a first coding scheme using a rectangular window and a second data of a second block encoded with a second coding scheme using a non-rectangular window, the method comprising:
generating, by an audio processing apparatus, an output signal for the first block using the first data of the first block based on the first 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 the window of the second block belongs to a transition window class, and wherein the window of the second block has an ascending line with a first slope. ]
