Apple Hi Rez - Bit Perfect?

[NOMBEDES]

I would encourage our founder, Chris to apply his most excellent skills to the upcoming release of high resolution music from Apple.  Chris has provided us with honest reporting on Sonus and BlueOS.  I await his contribution.

 

While I have your attention allow me to rant on the dishonest shills employed by various consumer tech outlets which continually report "leaks" regarding the various phones, pads, computers and what have you.  I submit that there are no leaks.  Stealth press releases, click bait, marketing, dreck.  Lazy lay-abouts scoop up what ever crap the tech companies are pushing and pass them on to their respective platforms reported as exclusive information.  What a crock.

 

Here is my leak.  A cell phone is a rectangle.  Some large, some are small.  Every so often there is new chip, a better camera or new screen technology, but hey, it is an overpriced rectangle that will never change. 

 

Thank you for your kind attention,.

There is a a macOS "helper" app called BitPerfect, but it seems to suffer from not keeping up with how each iteration of macOS CoreAudio changes the API.

 

I'm curious to know how people will get bit perfect playback of the new Apple Music content as well.

Typical click bait.. 

 

Not even mentioning the fact that there are no 3 dimensional rectangles

If I connect my phone to an external DAC using the USB Camera adaptor, lossless files playing from Apple Music do have the correct bit depth and sampling frequency. The question is, if there are no other apps open and the phone is on silent so there are no system sounds, do you then get bit perfect playback? It would seem to make sense given that there are no other sounds in the mix, but with Apple, who knows.

 

You can use an iPhone as an audio input device in GarageBand. You can record the digital output of the phone, but only up to 24/44.1. One experiment to run would be to load a 24/44.1 lossless file into Apple Music, play it back and capture the digital output with GarageBand, and then compare to the original file. If it worked, we would at least know that Apple Music in iOS is capable of bit perfect playback.
