Abstract
The MPEG-2 AAC standard uses both long and short windows. However, the use of short windows complicates the implementation of decoders as well as encoders. In this paper, we propose a method based on the modification of the amplitude of the time-domain signal to replace the function of short windows. Compared with the use of short windows, the proposed approach is relatively easy to implement. The subjective experiments show that the proposed approach is a promising alternative in coding transient signals.
