-The band IMDCT is a standard 128-point (input) IMDCT, yielding 256 output points. The window for the IMDCT can be steep or soft, which can be chosen for the right half of the current block and is reused for the left half of the next block. As with ATRAC3, the coefficients of odd bands are stored in reverse order.+The band IMDCT is a standard 128-point (input) IMDCT, yielding 256 output points.
