MP3 audio parallel decoding based on Libmad library
Xiaxin Li, Shutao Sun · 2014
With the popularity of parallel computing, the serial program is unable to take advantage of the multi-core. In this paper, A MP3 audio parallel decoding algorithm based on libmad library for multicore platform is proposed to improve the decoding speed. In this method, to reach the parallel aim, more than one decoder is provided. Experimental results indicate that the algorithm improves the efficiency and the parallelization. The decoding speed with 4 threads on 4 processors achieves a 60% performance increase compared to the traditional MP3 audio decoding based on libmad library.
