IOS 13 DOES PLAY FLAC!!!!!
I was able to Airdrop FLAC files from my iMac to my iphone (7) running iOS 13.5. I downloaded them to the iPhone. And now - when I click on the .flac file - it plays. And it plays natively, like in a file manager - NOT through iPhones. This is great. This is what happens when the iOS dev team is kept separate from the iTunes dev team.
Now - How do I get an equalize on my iPhone to work with the .flac files?
