Why can't I add my OGG music to iTunes or play it on an iPhone? Apple's ecosystem has never supported the open format natively, so converting to AAC or MP3 is the only way in.
About AAC
AAC (Advanced Audio Coding) is the lossy audio codec standardised in MPEG-2 and MPEG-4 as the successor to MP3; at the same bitrate it generally sounds better than MP3.
It is the audio in most MP4 videos, in Apple Music and on YouTube; a .aac file is a bare AAC stream without a container.
A bare .aac stream has only limited room for tags and cover art, so music players usually expect AAC inside an M4A file.
Why convert music to AAC instead of MP3? At the same bitrate AAC sounds better, and every modern phone, computer and streaming service decodes it.

- The audio is decoded and re-encoded as AAC at the default settings, so the result is close to the Ogg Vorbis but not bit-identical.
- Ogg Vorbis and AAC are both lossy formats, so this conversion adds a second round of lossy compression; keep the original Ogg Vorbis if you may need the best quality later.
