This paper presents a new high-performance audio compression algorithm for wireless application. Based on blue-tooth SBC algorithm architecture,the proposed algorithm adopts nearly perfect reconstructable proto filter and dynamic bit allocation technology to improve audio quality and performance. This algorithm was implemented on 32-bit CKA5102 MCU,and successfully applied to current wireless audio solution. Experiments show that compared with blue-tooth SBC,the proposed algorithm gains much improvement on audio quality,while having less cost in bitstream and power.
