Hey guys so Apple Lossless is both 44.1kHz and 48kHz
Anyone found any 48kHz music? Can you share the album?
I want to see if Apple Music on macOS automatically changes sample rates of my USB DAC
So far I only found 44.1kHz
It doesn't, I'm afraid.
I have switched on the Lossless tick box in Apple Music Preferences on my Mac, and selected High Resolution Lossless from the option drop down. Many albums now show the "Lossless" or "Hi-Res Lossless" logos. However, they do not trigger my SMSL M500 USB Dac's display, which stays stuck on whichever resolution was previously showing from the song most recently played via my Roon player (which has Tidal and Qobuz sources).
To be clear, on Roon, I can play:
- Yello, Stella, from Qobuz (FLAC 44.1kHz, 16 bit) -> My SMSL DAC display shows the "Green USB" 44.1kHz logo), then play
- Maroon 5, Songs about Jane, from Qobuz (FLAC 96kHz, 24bit) -> My SMSL DAC display shows HiRes Audio logo with 96kHz
- I can flick between these songs and the SMSL DAC display correctly updates to show the expected bitrate source material
On Apple Music, though:
- Yello, Stella, from (Apple Music "Lossless") -> My SMSL DAC display stays stuck on whatever it was from the most recent song from Roon
- Marroon 5, Songs about Jane, (Apple Music Hi-Res Lossless) -> My SMSL DAC display stays stuck on whatever it was from the most recent song from Roon
- I can flick between these songs and the SMSL DAC display doesn't budge at all (it stays stuck on Hi-Res Audio 96kHz logo, if I previously played such a song from Roon, or stays stuck on the "Green USB" 44kHz logo, if the previous Roon song was a 44kHz or 48kHz FLAC song).
Apple Music is doing something weird - and it isn't sending changing bitrates through to the USB DAC. Apple Music Lossless should be sending music at 44.1kHz or 48kHz, and Apple Music Hi-Res Lossless should be sending music at 88.2kHz or higher. It simply isn't.
