Airplay 2

According to this article from March 2023 on the What HiFi website(see below), using Airplay 2 will change the music file in Apple music from lossless to lossy. Apple was said to be working to fix the problem. Has this been fixed yet?


As we have noted in our lossless audio explainer, the AirPlay 2 protocol supports lossless music (audio up to 24-bit/48kHz, in fact) so those with music files stored on their iOS device can send it over AirPlay to another device losslessly. However, the news isn't so good with regards to using AirPlay 2 to send lossless Apple Music streams. Apple Music’s Lossless streams supposedly convert from ALAC (Apple’s lossless codec) into AAC (Apple’s lossy codec) at a pretty lowly 256kbps when transmitted over AirPlay – and therefore not losslessly. 

In other words, yes, AirPlay 2 does support lossless audio, but perhaps not for the use case you might want it to.

Apple is apparently working on an update to enable lossless over AirPlay (we are reaching out to Apple to confirm), so fingers crossed that this transpires and thus Apple’s lossless offering becomes validated.

Looks like Apple is now streaming Apple Music at CD quality (pcm/44100/16/ ) over airplay. Below is a test I did using a number of Apple devices to a Blusound Node 2i streamer. I used http://myplayer.blue/ to check the bit rate on the streams going to the Node 2i. I used the Stones Hackney Diamonds album for the source, 24 Bit for Qobuz and Apple Hi res for Apple Music. Bluetooth was AAC as expected.

This is my concern. If he played from the Blue app, I dunno. He needs to send this via Apple Music on iOS to really know. But then, he could not use this test web site. So someone with the right high end audio DAC needs to do this with something minimal like an Airport Express v2 with firmware updated to latest. Then we can be sure.

BTW, you can downgrade an Express v2 to an older firmware to force other sources to send only Airplay 1 to it. I do that. Until Apple fixes this. I also use Airfoil which shows, it is possible to send 16/44 to Airplay 1 and 2 devices at same time (from a Mac, at least). I think it runs in exclusive mode, which may be what Bluesound is doing as well.

Rob_F1: I'm not an engineer, like Steve, so your graphs are gibberish to me. :-)

I use Apple Music. I solved it by downgrading my Airport Expresses v2 to last Airplay 1 firmware. No matter what resolution is sending, it is always 16/44 lossless (as that is all I own in my collection or play from Apple Music).

But yes, you have discovered what many have found. Airplay 2 depends.

Since I play to better office or living room or bedroom systems individually, the Expresses is fine in there (with a little better AKM DAC on each). I have some MusicCast speakers and some HomePod minis and for those, Airplay 2 is fine for multi-room. The Apple Music app or iOS will not let you play to Airplay 1 and 2 at same time. A check mark in circle is Airplay 2 for iOS. Just a checkmark (only possible one at time) is Airplay 1.

Also, if you use iTunes Remote (AKA Remote app) on iOS, it will play your own music library from a Mac 16/44 lossless. But, Remote has been buggy lately.

If you use Airfoil on a Mac, all of this is gone. It will play both to Airplay 1 and 2 devices at same time and is 16/44. While Apple Music for MacOS doesn’t have an exclusive mode, Airfoil is exclusive. It bypasses the Apple audio processor - the cause of much of this. But, Mac only.

So, no fix yet for this. :-(

I also play CDs… :-)

I'm confused. Does this reduced streaming occur only with music streamed through the Apple Music subscription service or does this also occur with music that resides in your computer as digital files? I realize Rob_F! says everything is up to CD quality again, but I want to clear up if this was just happening with music streamed from Apple Music or with files stored on the computer.

If the check mark for Airplay Speakers & TVs is just a check mark, it is lossless 16/44. If the check mark is in a circle, it is probably AAC 256. The Airplay receiving device matters more than the sending device since an Airplay 2 sender must match reciever type.

But, I would not fret over it. It is impossible to tell the difference. The quality of the recording is a much bigger factor in the quality of playback versus lossy or lossless.

Files played from a Mac to an Airplay 1 receiver, like ripped CDs or downloaded lossless music bought online (not from Apple except if you download lossless file from Apple Music streaming subscription [rental music, essentially, you do not own it]), will play 16/44 lossless, the max that Airplay 1 will send.

I play my rips all the time from my Mac to my DAC via Airplay and they play 16/44 since the DAC gets its data from an Airplay 1 receiving device. I control my Music library using Remote app on iOS.

If you run a wire from your playback device, and it has a higher resolution file on it, and your DAC is capable, and the recording is high resolution (few are), then you can do whatever you want.

But, I would not fret over any of this audiophile nonsense. It is impossible to tell the difference. The quality of the recording is a much bigger factor in the quality of playback versus lossy or lossless.

Thanks for the answer, Ataraxy01. One little follow up / clarification, if I may:


My sending device (iphone) is using Airplay 2. The receiving device (external Naim wireless speaker) is also using Airplay 2, which I have confirmed based on the check mark in the circle.


The files I am playing from the sending device are downloaded lossless files from Apple Music. Even though they are downloaded and not being streamed, will they still be downgraded to AAC, based on both sending and receiving devices using Airplay 2?
