| Output codec | libvorbis |
| Setting | VBR quality 5 (~160 kbps) |

What changes
- Both AAC and OGG are lossy, so this is a second compression pass over already-compressed audio. It is fine for everyday listening and bad for archiving.
- Cover art, lyrics, and most tags are not carried across — the output keeps the audio, not the metadata around it.
