![]() ![]() ![]() Thanks to all who have posted to this thread. Anyways, it would be nice to have confirmation from someone else that his solution works. The Audio Midi Setup might be a way to control that. I told him my concern about the sound card resampling to 48 kHz, but he hasn't responded. It sounds reasonable, but he never mentions the sound card. This guy has a blog post on bit perfection by changing only the settings. If you have some experience with this, please point me in the right direction. (I don't think it matters much, but you're welcome to school me on that.) I'll be using USB because my laptop doesn't have the other thing. Also, it would be great if I could still use the iTunes interface. ![]() Now, there are some free programs, but I have principles I'm not going to download unnecessary programs or replace my sound card if I can just change the settings. Some claim it's easy to achieve bit perfect output by adjusting settings in iTunes and Audio Midi Setup (one of the standard Mac utilities), while others say it's impossible without better music playing software ($$) and the right sound card. What I do care about, because others have asserted that this happens, is iTunes monkeying with the signal and my sound card resampling everything to 48 kbps, for example. I don't care about that, jitters, or slight errors. What I mean by "bit perfect" is this: the files on my hard drive or CD drive are decoded and the data stream is given to the DAC without any resampling or signal processing in the middle.įor some people, bit perfect refers to the timing and shape of the signal waveform. For now, since I'm using a nice DAC, it makes sense to send a signal that's true to the source. I'll eventually start collecting better quality files, don't worry. Most of my music is in the form of AAC 256 kbps (44.1 kHz). I want to use an external DAC with my Mac laptop. ![]()
