In this paper, we propose an audio transcoding algorithm for mobile multimedia applications. The algorithm is to provide high quality transcoded audio stream from a multimedia broadcasting media server system to mobile terminals. As a representative case, audio transcoder between T-DTV and T-DMB service is considered. While the Korean DTV audio standard adopted the Dolby AC-3, the Korean T-DMB service uses the MPEG-4 BSAC. The proposed algorithm reuses the bit allocation information of the AC-3 decoder in the process of BSAC encoding and simplifies the bit-allocation process with two independent loops instead of nested ones. We verified that our architecture could take the place of the nested loop with a significant simplification and no PAM. The proposed audio transcoding algorithm is suitable for the mobile multimedia applications due to its low complexity and minimum frame-by-frame complexity variations
