Bit Perfect with a Mac

post #1 of 13

Thread Starter 

I will soon have a 2010 Macbook Pro.

If I use my Aune DAC through USB with iTunes, is it bit perfect or do I need to do something beyond that?

 

Thanks!

It may not be bit-perfect out of the box.

But set up iTunes and Audio MIDI Setup properly and you will get bit-perfect output through USB.

 

In iTunes make sure:

- "Sound Enhancer", "Sound Check" and "Crossfade Songs" are turned OFF.

- The EQ is turned OFF.

 

In Audio MIDI Setup make sure:

- The output format match the one of the played back audio file(s). Ex. 16-bit/44.1kHz for audio CD.

Hi Kai, just bought my first iMac! Where is the Audio MIDI Setup? I can't find the equalizer on iTunes.

I am not on my Mac right now, so not exactly sure where it is located. But just open Spotlight (top right corner) and type "audio".

I believe you find the iTunes EQ under the "Window" menu.

 

Congrats on the fresh Mac. :D

It sure can't hurt to double-check, but iTunes should run bit-perfect on a Mac straight out of the box with no fiddling. When I double-checked my new MacBook Pro a few months ago, everything was pre-set as it should be. Congratulations on a great computer and music server.

Audio MIDI Setup is located in the Utilities folder: Applications/Utilities

 

You can also shortcut to the Utilities folder by pressing: Shift+Command+U from the Finder

The EQ can be found in the "Window" menu when in iTunes, or just hit command-option-2.  If you have a mixture of 16/44.1 and 24/96 files and don't want to stuff around, just set Audio-midi Setup to 24/96 and be done with it. Wont make any audible difference.

Oh, you may also want to setup your USB DAC as an aggregate device in Audio MIDI Setup.

Thanks, found the equalizer and it is currently off as it should be.

Doing well, Miguel, I hope you are too. I'm still deep into computer audio, though I've simplified, acquired some active speakers and focused on music instead of gear. I'm becoming a jazz fan in my old age...

Jazz is what I listen to the most, although not enough time to do nor enough money to buy more music! Cheers.

Does this help in some way?

The used CD store is your friend, Miguel. I'm shocked at the stuff I've found there at 50 cents on the dollar. Time? A glass of wine and a pair of headphones after the family has gone to bed. I'll sleep when I'm dead
