Apparently Apple allows apps to modify audio now. EffectDeck, can increase the volume of your earbuds, without making them sound like shit.
My preset for Bose wired earbuds.
Don’t think it does game audio though. Also, opening Philo, it says unable to connect to EffectDeck.
I won’t use EffeTune on my desktop, looks like they used AI. This app probably used AI too. Don’t know of any other apps that do this though.
