Settings this conversion runs with
| Engine | ffmpeg |
|---|---|
| Output codec | libmp3lame |
| Setting | VBR quality 2 (~190 kbps) |
| Compression | Lossy |
What changes
- Both OPUS and MP3 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.
