Okay. As someone who uses a Mac, this peeves me off. Does he know that you need to use earbuds or headphones???? To get decent audio off any computer??? And not just any earbuds, like, actual decent ones??? Also, has he actually used Fischer Price's toys?? Also, if you're gonna record professionally, it's better to go for desktop because they have more power.
Lmao. I've used both Mac and Windows PCs and the Mac wins out for better speaker quality, but I still wouldn't try to mix playing the audio out loud on laptop speakers. Also, Garageband is a good DAW; it has pretty much everything you need right there and MP3 isn't the default option, anyways. Garageband by default exports to M4a, which more HQ than MP3. If he's so concerned about "teens" (it's not just teens, anyone can make the mistake of using MP3) using MP3, then why not just be like "hey, PSA: 'don't use MP3 it messes up the audio quality'".
I don't even like this phrase, but it seems appropriate here: "OK boomer".
(Sorry if I sound rant-y.)
