Abstract
In this paper, block backward adaptive linear predictors are used for improving the performance of perceptual audio codecs. Based on the investigation on different linear prediction algorithms, a signal dependent adaptive-switched predictor is developed. This predictor not only delivers significant coding gain for stationary signals but also recovers quickly from transient signals. At a bitrate of 64 kbit/s, the performance of the new codec for most critical test sequences is significantly better than MPEG-1 Layer II
