纯讨论：audirvana3.5.43播放非DSD音乐文件，界面右下角显示解码位数？

如题：播放DSD文件时，无论升频不升频DSD播放就原码输出，比如64的就输出64，128就输出128.这没有问题。如果是WAV或FLAC\APE格式音乐，在不升频的情况下，（外接解码为32-384）原码是16-44.1，则输出为32-44.1；原码是24-96，则输出为32-96；也就是说升频不升频，输出位数始终为32BIT。按照官网上说的：右下角显示是始终是外接解码的参数，而不是实际输出参数，实际输出参数还是16位或24位原码bit数值。

如果升频情况下：DSD格式升频不了（不像HQPLAYER可以升频）。wav、ape或flac格式，采样率可以按照设置的参数进行升频，比如：16-44.1升频为176.4，则显示为32-176.4，176.4好理解，此时32bit是升位数了，还是如上面说的实际为16bit，显示的32只是外接解码的参数显示。

如果DSD格式转为PCM输出听音乐，此时界面右下角显示基本为外接解码的位数，比如：外接解码是32位，则显示为32；外接解码是24位，则显示为24位。这是实际音乐输出位数应该是16位还是显示的24位或32位呢或其它的位数呢？作为使用者如何分辨真实的位数呢？

是不是说：升频不升频，最后变化的只是采样率，而位数不会变化（一直保持原音乐的位数）。可以这样理解吗？

Hello @ssxbb9855,

Your DAC only support 32 bits, this is why you always see your output in 32 bits even if you are playing a 16/44 or 24/44 track, Audirvana will always adapt to your output and it capabilities.

8

那实际输出是32位，还是多少？我不想让他升级我的位数。我只想原码16或24位输出。

9

再有，当DSD转PCM输出，此时的右下角的32bit输出是仅显示为32bit还是实际输出为32bit，如果不是32bit输出，那是多少bit输出。能不能查到或监测到实际输出bit，而不是仅仅显示外接解码的bit，因为外接解码的实际最大采样率和位数在说明书已经说明了，不用在AUDIRVANA界面上再显示，我说的对吗？谢谢！

Audirvana do not add bits, it just take your output capabilities and send the audio to your DAC as it is, that’s all you have to know. If you are worried about having 16 or 24 bits as you are using your DAC, contact the manufacturer of your DAC as it’s a 32 bits only DAC.
