Audirvana plus正版软件,播放sacd iso文件时有明显底噪,什么原因?

bigmusicfan

我是新买的Audirvana plus 1.5.10 正版软件，播放sacd iso 文件用DSD播放有明显的底噪音，播放Blue Coast 下载的sacd 文件就没有问题，转PCM 352.8也没有问题， 知道可能是PREFERENCE 设置问题，哪位师兄可以帮帮我？

bigmusicfan

我用的是新买的Audirvana plus 1.5.10 正版软件，
1、播放sacd iso 文件DSD 播出有明显的底噪音，播放Blue Coast 下载的sacd 文件就没有问题，
2、DSD Over PCM 352.8也没有问题，
3、解码器是Playback Designs MPD-3，也没有任何问题。
可能是PREFERENCE 设置问题，哪位师兄可以解释一下？

樓主, 請試用一台PS3 rip (DSF檔案) 一下身邊SACD....再比較一下吧

你試下係 audirvana個 audio filter 度set下，嗓音問題多數由佢引起

bigmusicfan

请问gorgeous：在audio filter 中好像只有二个set，要哪一个？

我都有同樣問題，試過所有low level playback option, 包括auto detection, DSD over PCM, integer mode 1 & 2 , direct mode on and off.............  燥音還在.   就算問 Audiranva 答案係以下

Depending on the version of the firmware, the DSD streaming method can change for the Playback Design DACs. Can you try with "DSD over PCM 1.0" method (Audio system page of Audirvana Plus preferences) instead of "Automatic Detection"?

答案從Playback Design 更利害

I believe this is an issue for the developer of Audirvana. Are you sure
that Audirvana recognizes the ISO file?

I am using the playback MPS3 with Audirvana Plus, there without any noise came from even playing the SACD ISO

TO josephlai: 这个问题苦恼我几个星期了，现在有一点点眉目：
1，你用的是哪个解码器？PLAYBACK DESIGNS MPD3肯定是可以完美播放SACD的，我播Blue Coast下载的sacd用DSD播放就没有任何问题。
2、问题的关键是，Blue Coast 下载的文件是DSF文件，而SACD ISO是光盘镜像文件，里面是不是都是DSF文件就不一定了，我现在正在研究中。
3、难道我要把4T的SACD ISO全部转换成DSF？呵呵，工程太大了！！！

bigmusicfan

TO manwong3000: 你是如何SETTING Audirvana ?

bigmusicfan

TO josephlai & manwong3000: 我觉得问题可能不在PLAYBCK DESIGNS MPD3 ，
问题出在Audirvana plus 把SACD ISO 解码为 DSF , DFF 这里。

请注意：Are you sure that Audirvana recognizes the ISO file?

I am sure that Audirvana recognizes the DSF file!!! Only DSF???

josephlai

That maybe the case of Audirvana Plus.

I play some DSDIFF & DSF via my MSP-5 without problem at all, however, only problem with  ISO files with the same setting........

是的，我的也是DSF没有问题，ISO有噪声，你是哪个版本的AUDIRVANA?
难道有不同版本的AUDIRVANA可以读ISO?

Set the DoP 1.0, Mode 1 or 2 also without problem.  However, the program is not stable, easy the crash and need re-start again.

Thank you manwong3000,

you just mentioned that you play the Audirvana in Dop (DSD over PCM) mode , have you ever tried the DSD native mode?

Audirvana plus 1.5.10 at the same setting. Automatic detection, DSD natively:

1, When i play DSF files, it plays perfectly.

2,When i play SACD ISO files, it recognize the file, i can hear the music, but at the same time, there is a obvious noise.

3,You are right, when i set DoP 1.0, DSD convert PCM 352.8 automaticly , it runs perfectly at first. just after 1 or 2 or more hours, the music will not be coherent just on and off. at that time ,what you can do is re-start the A+.

It's so annoying.

It could be possible that your Mac is not fast enough to do SACD ISO extraction on the fly, or audirvana is not well written to support on the fly ISO extraction.
Why not try to get a trial copy of Jriver mac version to test and isolate your problem

i have contact with Damien, and send my debug information to him. his reply is so quickly, he is the developer of Audirvana, wish he can resolve the problem.

Mine is 1.5.10 and found the same problem via my Macbook pro & Macbook Air

i found  only way to play SACD ISO without noise
select NONE: convert to PCM,   tick 3 low leverl options,  it can convert to 352.8 autimaticly, the sound is good.

BUT, 1 or 2 or more hours later, the music will be uncoherently ,just on and off, enven pause at last.

i feel the version 1.5.10 has many problems in this part.
