摘要: Recently, lifting-based integer approximations of filter banks have received much attention, especially in the field image coding. The application techniques to cosine modulated for audio coding, including not only modified discrete Fourier transform (MDCT) but also low delay are focused on. Applications include lossless coding and backward compatible enhancement MDCT-based perceptual schemes, such as MPEG-2/4 AAC.
