So I know what AC3 means of course, but what does AC3D mean in some releases?

    It means Dubbed. It’s a short name for AC3.Dubbed

    The audio track(s) have been dubbed to match with the video track.

    The same applies to DTSD -> DTS.Dubbed

      Is this different from mic-dubbed and line-dubbed? My impression was that those only come as mono or stereo, but many AC3D releases have surround sound.

      Edit: So apparently dubbing is just the process of adding audio to a video track, sometimes replacing or complementing the original one. The quality dependends on where the audio comes from, but all of them are called “dubbed”.
