AB  - Current high quality audio coding techniques mainly focus on coding efficiency, which makes them extremely sensitive to channel noise, especially in high error rate wireless channels. In this work, we propose an error-resilient layered audio codec (ERLAC) which provides functionalities of both fine-grain scalability and error-resiliency. A progressive quantization, a dynamic segmentation scheme, a frequency interleaving technique and an unequal error protection scheme are adopted in the proposed algorithm to construct the final error robust layered audio bitstream. The performance of the proposed algorithm is tested under different error patterns of WCDMA channels with several test audio materials. Our experimental results show that the proposed approach achieves excellent error resilience at a regular user bit rate of 64 kb/s.
