I believe the lower bitrate you quote is for Apple Music and AirPlay 2 which transmits 256kbps AAC streams. The bitrate for CD quality streams is up to 1440kbps and as I say, I understand AirPlay 2 can achieve 24/48 which is even higher.256 Kbps
AirPlay 2 supports lossless, 16-bit/44.1kHz CD-quality audio streams1. The bitrate for AirPlay 2 is 256 Kbps2.
Airplay 1 is a different animal

Yeah, aware of that thanks, but in the context of WiiM and other non-Apple devices, I stand by what I sayPlease read my edit and link explanation of 24 bit Apple Music

Not really sure coz the volume seems to be changing when switching. Also im new to hifi so i lack knowledge on numbers and graphs but earlier while switching back and forth i could hear some difference, like cymbals echoing at higher pitch but maybe it’s just the volume/normalization…Spotify has a bitrate of up to 320kbps, and Airplay can support up to 24/48 lossless so I’d say it has more than enough bandwidth for it.
Can you hear a difference? You might be pushed hearing a difference even with Bluetooth.
As you say, it might be the normalisation as Airplay should be able to accommodate Spotify no matter how it’s being played.Not really sure coz the volume seems to be changing when switching.

Using airplay, this is what wiim’s says 900kbps 16bit 44.1256 Kbps

Explains the 24 bit on airplay and how you can get itApple AirPlay 2 supports 24-bit lossless audio, but you can’t use it
If AirPlay is limited to 16-bit CD-quality streams, how is the HomePod able to use AirPlay at a better-than-CD 24-bits?www.digitaltrends.com
Yeah, that’s fairly standard for airplay on WiiM, although I wouldn’t get too hung up with the 900kbps figure as it seldom varies and doesn’t really say anything about the resolution/quality of what it’s sending. Like ChromeCast and AlexaCast, they’d be as well not displaying that 900kbps as it’s potentially misleading.Using airplay, this is what wiim’s says 900kbps 16bit 44.1
Alright thankyiu!As you say, it might be the normalisation as Airplay should be able to accommodate Spotify no matter how it’s being played.
