摘要 高级音频编码目前被广泛应用,但其算法复杂度高、速度慢,无法满足实时性要求。从不同模块方面简要总结了几种高级音频编码的快速算法,为从事相关研究的工作者提供参考。 Advanced audio coding is a high-quality and popular audio coding standard. However, owing to the complexity of its algorithm, it is hard to satisfy the require for real-time implementation. In this paper, several approaches to implementing AAC fast algorithm are given.
