This describes the format of the audio track.

This isn’t a 4K remux, but for 1080p BluRay x264: Cars.2006.1080p.BluRay.x264.AAC-ETRG

✅ Verdict – Great for a 42–55" TV. If you have a 75" 4K screen, you’ll notice softness, but for everyday watching, this is a strong encode. This describes the format of the audio track
