Which audio track is best (DD or PCM) on Rocky Balboa?

#1 Post by camren » Mon Jul 03, 2023 6:46 am

I haven't seen a PCM audio track before and wondering which one is best to select.

Track #1 is AC-3 Dolby Digital, but is "Lossy", 640 kb/s bit rate.

Track #2 is PCM, 4 608 kb/s bit rate.

Thanks!

Strictly speaking, PCM is almost assuredly higher fidelity than AC-3.

That said, the PCM track might only be stereo, where the AC-3 very likely a 5.1 track.

I don't happen to have Rocky Balboa, so I can't comment specifically on it.

It looks like there is a review of the Rocky Balboa blu-ray on blu-ray.com. It says the PCM track is a 5.1 audio track and is highly regarded.

Your choice may also depend on your media player(s), some don't like "raw" LPCM audio.

AC-3 (Dolby Digital) is a pretty safe bet, it's like the universal donor of audio tracks and will most likely play on just about any player.
