How to Re-Encode Dolby Digital 5.1 without audible degradation?


I extracted Dolby digital 5.1(ac3) to 6 mono wav L R C LFE LS RS

and mixing my voice overs in channel C, then I Re-encode to Dolby digital with Dolby media producer suite. I listen re-encoded of Dolby ac3 and compare with Dolby ac3 original. I see audible degradation.

Hi.     Please only use this forum for questions about the Dolby Atmos Production Suite going forward.    Dolby Digital is a lossy codec for consumer formats.   It is not designed to be decoded and re-encoded.   Degradation would be expected.   You should contact the owner of the content for the PCM source.   Thanks,  Adam Dolby Labs
