Abstract
A simple and flexible bit-plane coding method is developed for scalable audio coding. It is different from the traditional bit-plane coding in that the optimal bit-plane scanning order is adapted to the scale between the energy of the residual signal and the audio mask. Both the perceptual quality and the lossless compression ratio at common lossy bitrates are greatly improved compared with the performance of state-of-the-art scalable audio
