I have since re-enabled BitPerfect, but only because I found that for some reason the Audio MIDI settings would randomly reset themselves to 44.1k periodically. I used to think it was, but after being educated by on how non-integer resampling can actually retain perfect analogue reconstruction of a digital signal within the Nyquist limit of the lowest sample rate involved, I tried setting my Mac mini music server's Audio MIDI to 24/96k permanently and then turning off BitPerfect, and I can't say I heard any audible difference in any of my music. BitPerfect is useful only if you want to be able to switch resolutions on-the-fly rather than manually (so you can, for example, play a 16/44.1kHz album and then immediately play a 24/96k album without pausing the playback and going into the Audio MIDI utility in between).Īnd of course BitPerfect is useful only if you feel that sticking with the music files' native resolution is necessary. I really like mpd, because I can control it from my iPhone or my Mac, or from the Mac terminal.Īh, now I understand what you are saying - thanks! And yes, that squares with my understanding too. I only have 2 ripped SACDs, but when I play the dsf files, the DAC now shows "2.82 DSD" on the display, and when I switch back to a CD quality FLAC is says "44.1 PCM." It has done it for every USB DAC I have connected. For some reason Apple adds a space to the end of the device name for the DAC. The two things here that tripped me up were:
J RIVER MEDIA CENTER WINDOWS 7 BIT PERFECT MOD
Mod happily switches sample rates on the fly and will even play DSD using DoP.īut I struggled setting it up, so I figure I would post the audio_output section of my config that finally works, so you don't waste 30 min figuring this out:
J RIVER MEDIA CENTER WINDOWS 7 BIT PERFECT FREE
But I really wanted to find a way to get this to work.īecause I am a cheap bastard, I wanted to find a free solution. To be clear from the outset, I'm in the "CD is as good as it gets" camp, when it comes to digital music. You can force it to 24/192 using the Midi Settings app, but then it's stuck there and when you play 16/44.1, it's upsampling everything. Particularly disappointing was Apple Music, that now supports up to 24/192, but the DAC will not auto switch to 24/192. Some are still in the Mac app store, but are pretty much abandonware, not seeing updates for as long as 3 years. There are players available which will do that, but they cost $10, $20, even $40, and often don't get good reviews. I have a Topping D10s that I bought based on Amir's review, and was deeply disappointed when I found out that most Apple music players WILL NOT switch sample rate and bit depth on the fly when you play a 24/192 song or a DSD file.
