What changes
- FLAC holds the full waveform, and OPUS does not. This pass permanently discards the parts of the signal the codec judges inaudible — keep the FLAC file if it is your master.
- Cover art, lyrics, and most tags are not carried across — the output keeps the audio, not the metadata around it.
