摘要

除了几种加性和非加性信息代价外，文献中还提出了基于代价函数的最小化来选择信号分解的搜索算法。我们引入了一个新的代价函数和一个基于感知准则的搜索算法。结果表明，在相似的比特率下，压缩音频信号的质量比初步方法更高。

An adaptive tree search algorithm with application to multiresolution based perceptive audio coding

Search algorithms for selecting signal decompositions based on the minimization of a cost functional have been proposed in the literature, in addition to several additive and non-additive information costs. We introduce a new cost function and a search algorithm built from a perceptual criterion. Their efficiency is demonstrated with results showing higher quality compressed audio signals than preliminary approaches at similar bit-rates.
