还是从废柴16/44开始吧

是不是很糟糕?IMD表现非常弱,就像当初那个解释创新src问题的文章里描述的一样。事实证明,HDAUDIO依旧无法绕过传统的SRC问题,16/44注定是垃圾表现虽然其他指标已经超过了很多声卡的水平。小熊在线www.beareyes.com.cn
找个竞争对手,谁呢?就se200的7.1输出吧

IMD的差距足以致命
那么,16/48如何呢?se200的16/48和16/44差不多的
不过hdaudio么:

注意IMD,已经达到se200 7.1的水平了!其他数据也不弱!不过么,16bit下的测试向来被我无视的。小熊在线www.beareyes.com.cn
24/88无法测试,那只能24/96了

是不是数据上已经看不出差异了?然后我们开始要比细节
