音频编解码算法的客观测试Objective Measurement for Audio Coding Decoding

摘要(Abstract)：
依据BS.1387客观测试标准,针对现有3种常用的音频编解码算法(MPEG2,AAC,AC3)进行客观测试,并对测试结果做了分析和对比。BS.1387标准是于2000年ITU针对音频感知音质提出的客观测试方法,简称PEAQ(The ITUStandard for Objective Measurement of Perceived Audio Quality)。针对该标准,对其测试方法模型进行了深入研究,并在Matlab软件中得以实现。通过与主观测试的对比,揭示了该算法的可靠性和准确性。
