这篇论文描述最近被 AVS 标准化了的一个一般听觉的编码算法,中国。算法基于一种感性的编码技术。在 128kb/s 的 CD 质量声音附近的 codecdelivers。这篇论文详细描述编码者结构并且为特定的设计方法讨论原因。主观测试结果的一篇摘要为原型 codec 被介绍。比较吝啬的意见分数(互补金属氧化物半导体) 测试显示 AVS 听觉的编码者的质量与 MPEG Layer-3 听觉的编码者是可比较的。一个即时解码器被用于描述测试,它基于 16 位定点 DSP。DSP 解决方案的性能被表明,包括计算复杂性和存储特性。
This paper describes a general audio coding algorithm which has been recently standardized by AVS, China. The algorithm is based on a perceptual coding technique. The codec delivers near CD-quality audio at 128kb/s. This paper describes the coder structure in detail and discusses the reasons for specific design methods. A summary of the subjective test results are presented for the prototype codec. Comparison Mean Opinion Score (CMOS) test indicates that the quality of the AVS audio coder is comparable with MPEG Layer-3 audio coder. A reM-time decoder was used for the characterization test, which is based on a 16-bit fixed-point DSP. The performance of the DSP solution was demonstrated, including computational complexity and storage characteristics.
