Re: Where are the audio quality settings on iPad OS 18.6.2?
There have been three updates available since iPadOS 18.6.2
You might want to try updating to the newest iPadOS 18 version
About iPadOS 18 Updates - Apple Support says: iPadOS 18.7.2
and "This update provides important security fixes and is recommended for all users".
____________
For iPadOS 18: See how to: Adjust the sound in Music on iPad - Apple Support
lists just
" ... EQ and Sound Check. Crossfade songs in playlists."
Seems those are the Audio Quality settings
Wondering whether or not you are an Apple music subscriber:
See how to: Play lossless audio in Music on iPad - Apple Support for all the details.
Eg: says:
"Apple Music subscribers can access millions of tracks encoded using lossless audio compression."
and
"Streaming lossless audio over a cellular or Wi-Fi network consumes significantly more data. And downloading lossless audio uses significantly more space on your device. Higher resolutions use more data than lower ones".
"Note: Apple Music and lossless aren’t available in all countries or regions.
See the Apple Support article Availability of Apple Media Services."
