M4A vs OGG
M4A
An M4A file is a compressed audio format (usually AAC inside an MP4 container) used by Apple's ecosystem — iTunes, Apple Music, and voice memos on iPhone all default to it. Slightly better quality than MP3 at the same file size.
Used in: Apple Music & iTunes · iPhone voice memos · Audiobooks
OGG
An OGG file is an open-source compressed audio format, an alternative to MP3 that's free of licensing restrictions. Common in video games, open-source software, and some streaming services.
Used in: Video games · Open-source software · Some streaming platforms
