foobar2015

@tmtomh Awesome! Thanks for your answer! I saw my DAC change its sample rate when changing this in Audio MIDI setup. This should be PCM bit perfect between foobar2000 in Mac to my DAC. Do you have any theory or practical reason that down sampling to different ratio between 48X and 44.1x causes audible differences? I tried several different ratio but I can't tell the difference.

Guys, my question is on how Wine in Mac interacts with coreaudio. I don't plan to compare PCM vs. DSD. TBH, what really matters the recording quality of audio source. @Iain, I'm using foobar2000_input_sacd plugin to decode DSD into PCM. The upper limit on PCM sample rate is 352.8Khz. I can't tell difference after setting up to 88.2Khz. My Fiio X3II DAP can use as DAC and may be able to decode DSD by DoP. But I haven't tried it yet because I haven't figure out how to use WineASIO driver yet. One of reason I will use foobar2000 to decode DSD is multi-channel record and only listen to FL and FR channel. Fiio X3II can't handle multichannel music correctly (not just DSD but also ALAC and FLAC)

I love foobar2K. But I dislike Windows. So I ran foobar2000 in Mac and Linux Fedora 23 with help from Wine. In Fedora, I knew that ALSA can be a bit perfect solution that audio would not up/down sample again with proper configuraiton. But I'm not sure how I can do that in Mac with Wine. I found some Wine source code using coreaudiod. I can't find any details regarding Mac audio system. Sometimes, I wonder if bit perfect really matters. For example, foobar2K SACD plugin converts DSD/DST into PCM. It is lossy transformation. It is not bit perfect. So why am I so obsessed with this kind of thing?
