摘要 M PEG音频编码标准的实现算法比较复杂,而目前对该算法的优化大部分集中在在对算法的简化上,以减少运算量,在这方面已经有了很大的发展,通过从算法编码实现上,讨论对M P2编码算法的优化。 It is complex to implement MPEG audio encoder, and the optimization on the algorithm is based on reducing the operation during the process of audio encoding. We have got great progress on this. In this paper, we will discuss how to optimize MP2 audio encoder in program codes.
