| 摘 要： | 为了对AVS标准音频部分的编解码质量有一个客观评价，2005年8月，AVS标准工作组组织会员单位对AVS音频和LAME MP3进行了内部主观测试，测试结果表明：AVS音频强于LAME MP3；2005年底，AVS音频技术和EVD的ExAC音频技术进行了融合，为了验证融合的效果，又进行了一次主观测试，测试结果表明，融合后的AVS音频编解码质量得到小幅提高。

| Abstract: | For obtaining an objective evaluation of the codec quality of A VS audio part, A VS workgroup organized some members to have inside subjective assessment of A VS audio compared with LAME MP3 in August 2005. The test result indicates that the codec quality of AVS audio is better than that of LAME MP3. In the end of 2005, A VS audio technology combined with ExAC technology of EVD. For verifying the effect of the combination, another subjective assessment was taken and the test result indicates that the codec quality of combined A VS audio has been improved a little. |
