Apple Music High Res

Um, that ain’t right. It’s Audio Interchange File Format, and it always has been.

I think back at Apple we used “Apple” interchangeably with “Audio”. But point taken.

Lol. All this confusion about Apple Lossless and how to get it to actually play. Similar to Amazon, they are just checking off a box. Next!

Haha you mean shouting at the clouds on this forum won’t work?

:crazy_face:

I have proven both steps (1) and (2) for 16/44.1 are lossless by playing Fairytales (MQA) from iPadOS 14.6 → AirPlay1 Lumin (at max volume) USB output → Full MQA DAC that shows MQA.

AirPlay2 to other streamers become AAC.

Same as the AudiophileStyle article showed. But his conclusion that Apple Music streaming is not bit perfect is strange (despite him confirming the same MQA finding as you).

Nice job ! Thanks

There are differences between AudiophileStyle investigation and mine:

  • AudiophileStyle tested USB output
  • I tested AirPlay1 and AirPlay2 output
  • AudiophileStyle did HDCD tests and the conclusion is based on that, he does not trust MQA
  • I only tested MQA CD. I would like to perform HDCD tests too, but we do not have HDCD hardware decoder. We even checked the Denon we have, but it seems they no longer supports HDCD.

Yes all noted. I will be testing USB output with the FairyTale MQA album next week.

I saw in the comments section of the AudiophileStyle article someone questioned the validity of the supposed HDCD stream from Apple Music. Certainly raises eyebrows, given the MQA album works.

More testing next week. Until then, back to enjoying the music :grinning:

Some 2L MQA albums on Apple Music that can be verified via AirPlay1 to Lumin to an external USB Full MQA decoder DAC:

  • 16/44.1 Fairytales MQA
  • 16/44.1 Mozart Violin Concertos (MQA)
  • 16/44.1 Lux (feat. Trygve Seim … )
  • 16/44.1 Polarity - Hoff Ensemble
  • 16/44.1 Reflections - TrondheimSolistene
  • 16/44.1 Utopias - Radical Interpretations …

Also, I also think that lossiness/losslessness (had to write this, lol) can’t possibly be related to volume levels. There is a catch but I am unable to catch it. So, the Lumin issue is still open for me.

What issue?

Say this out loud a few times :joy: losslessness

At least we have @wklie who’s having fun with the testing and needless to say we’re very grateful.

I have proved the losslessness.

If the question was why Lumin web page suggests max volume. It needs a few lines of explanations.

If you are using Lumin digital output to another DAC, you have to keep the Lumin / AirPlay volume to Max such that Lumin is not applying digital volume for output to the external DAC. Likewise re-sampling needs to be turned off.

If you are using Lumin analog output using built-in DAC, the AirPlay volume does not affect the losslessness.

Sorry if I am not current on the messages, but I just read that Lumin says AirPlay to Lumin device will be lossless if the volume is set to max on the i-device. This made no sense to me. Has the reason been revealed since then?

It quickly became Loch Ness, which is also another troublesome entity :slight_smile:

Eh, there are no degrees of losslessness, it’s like being pregnant. Either you is or you isn’t.

I’m fairly confused by Apple’s offering of lossless .
1)So using airplay from my phone to a music streamer is currently AAC and not Alac ? What about from my Mac ?
2) Would Apple Music listing 16/44 play to a dac that only shows 24/44 on Audio MIDI ( no 16 bit available as a option ) be up sampling or bit perfect . From a Mac computer .
3) Is using IPhone USB to connect to CarPlay in your car playing lossless when it’s marked as lossless or AAC ?
