So I'm using a mac mini to a Sony DAC (UDA-1), but I can't seem to adjust the resolution when in DSP and output format past none. The audio device says Sony USB Amplifier (Core Audio). The Sony DAC does up to 4XDSD. Anything I try just produces static.
-
Could it have anything to do with the connection from the mac mini to the Sony DAC?
-
What connection are you using? USB?
-
I have been using USB, but I have the option for toslink from the headphone jack.
-
Are you saying that you are unable to change the sample rate in the DSP screen? If you're using the usb, have you loaded the correct drivers?
I would try the toslink connection to ensure you can get some sound from your system and then go back to usb for the HD sample rates your DAC can use.
-
There's a chance you might need to open the Audio MIDI Setup app on the Mac, and set the Sony DAC to the highest bit-depth/sample rate supported. This is required for some DACs with Mac, especially when trying to do DSD.
-
Donkey, I think that's it! Having never dealt with this Apple MIDI, should I just max everything out as my DAC can handle anything thrown at it?
-
Well, just for the Sony DAC you should max it out. Like I have here at 2ch 32-bit/192 kHz: https://i.imgur.com/AEU9uSh.png

Mr. Donkey, now that you've helped me with that, any tips on converting formats for a large amount of audio files quickly?
-
Select, right click, convert.
Try a few before you do very many.
-
Thanks for the reply, I can get it to work, but I have almost 25,000 files to convert. I've done about 3000 a day so far, just trying to see if there was a quicker way.
-
There is no limit on how many you can convert at once.
It might help to understand why you're converting. From what to what?
-
I have a new car stereo (Kenwood DDX9904s) that plays FLAC files. I have about 25,0000 songs, some were FLAC but most were ALAC or M4A...so I have to convert everything to FLAC.
-
3,000 a day on Mac hardware sounds about right. Don't think there's anything you can do to "speed" up the process - it's likely going as fast as it can.
-
Now it keeps freezing, It's on 18106 of 23578...been freezing last two days...
-
It's probably not freezing. The OS just can't get a response. Let it run.
-
Jim, even though there is no movement and I see nothing being done?
-
Open Activity Monitor (in Applications -> Utilities).
If it's really not doing anything, you will see ~0% CPU activity.
-
I'll do that, could it also be getting hung up on some very lo-res aac file I might have gotten years back?
-
So yep, every time the conversion "freezes" for a couple hours, it's when it hits a low res, lower bitrate file.
-
Please send us a file that causes the problem.
-
JimH will, do...what's the best way to get you one of these files?
-
If it's small enough, send it to johnt at jriver and include a link to this thread. Otherwise post it on dropbox or similar.
