  1. Indeed. The same video was shared on Roon forum and I replied that he showed the sample rate matching which is automatic on iOS and iPadOS. The bit perfect issue isn't covered. Moreover he claimed two times that 48 kHz is possible via AirPlay which isn’t true for audio only streams.
  2. It seems that nothing has changed: https://community.roonlabs.com/t/apple-music-high-res/159869/1249

  5. Clever. My relatively recent Mac (2018) doesn't have TOSLINK (neither in nor out).
  6. It's interesting to observe that the Shairport Sync recording via stdout compared to the original FLAC file in a multitrack session (all three 16 bit) isn't bit perfect. The result is audibly muted, the volume levels the same and yet the Frequency Analysis shows that it's not perfectly nulled.
  7. @wklie I listed Loopback app in my previous reply when you mentioned a virtual soundcard driver. FYI, I have Loopback installed on my machine. Keep in mind that a slight latency is involved: ~20 ms. P.S.: did you take a look at my Roon message covering the iPad recording? It's a too complex process, isn't it?
  8. Out of curiosity: how did you manage the recording session between the iPad and the Mac?
  9. I analyzed deeply the tracks comparison during playback: At -140/-160 dB there's a difference. Not audible of course and the level meters don't move. Still there's a difference – not bit perfect. It's highlighted here: Intrigued by the result, I picked my previous test where I compared 6 different recordings with the original track and looked at the same detail level. The results: The loopback track (track #7 – basically the same as track #2 above) shows the same difference at around -170 dB confirming what noticed today – No
  10. @wklie Do you mean something like BlackHole or Loopback?
  11. 😀 I speak for myself: no. At least, not in a relaxed way, as it should be. I do listen without all these bit perfect/lossless/whatever distracting thoughts between the tests, though.
  12. I redid the test. I'm using the same album over and over again because it's the only album I bought after the introduction of Apple Music. Every previously matched album is unfortunately still provided by Apple's servers in AAC. It's a common issue. This time, at least, I changed the track. 🙂 I tried to provide as much informations as possible, documenting every step. My obsession with graphic produced a tall image. I divided it in three pieces. I hope they are usable (download it, in case). Part 1/3: Part 2/3:
  13. @seasonsinthesky For what is worth, I made some tests using the null method, recording the stream and comparing it with an original counterpart track. I could’t test AirPlay 2 because I don’t own an AirPlay 2 device. Actually I own two of them: an Apple TV and a HomePod. They simply aren’t suitable for testing for obvious reasons: Apple TV’s output resamples everyting at 48kHz and with the HomePod is impossible to know what it is receiving and, besides, it doesn’t support Apple Music lossless yet. My AirPlay 1 tests (iOS/iPad OS -> Mac and Mac -> Mac)
  14. I chime in even if I'm not Chris. 🙂 Unfortunately BitPerfect app doesn't work with Apple Music contents. Only local files (owned) are handled.
