| Abstract: | This paper presents a high quality coding method for wideband audio signalbased on combined orthogonal transform. The coding quality of the method isbetter than the traditional discrete cosine transform(DCT). The new method is morestable and has similar coding and decoding complexity with that of DCT. The experimental results are also given. |
