I have a little question...
If i do something like : "eac3to 00001.m2ts 3: c:\File.wavs" Track 3 is DTS-HD MA, either 2.0, 5.1 or 7.1. I have the decoderdtsdll.dll installed. Will the wave files be created only from the DTS core (so from lossy audio), or will they be created from the full DTS-HD MA information (the lossless audio) ? Thanks. |

It will extract the core if you tell it to with "-core" switch.
Otherwise, if Arcsoft decoder registered, then it will extract the lossless DTS.

I oddly find that when I'm decoding AC3 I have to force the switch -Nero. Yes, Nero 7 is properly installed, eac3to -test KNOWS it is installed (and says it works fine) and it seems to work properly when I add -Nero to my line. For some reason it doesn't seem to be the default decoder though.
Any thoughts on this? |

I don't think the Nero decoder does a better job at it, so the default choice here makes sense, IMHO.

-downmix and dithering.
I noticed that decoding the same surround source file with the -downmix option produced different output files each time (the samples weren't the same). I'm pretty sure that this is because there is dithering which is randomly chosen. Sure enough, when I specify "-full" as suggested by madshi, the output is identical every time.
My question is how exactly is the random noise seeded/generated and why not just use a method (i.e., same seed) that produces identical results each time? I know it would put my mind at ease a little. |

Oblivion: distorted center channel
While waiting to be able to post here for the first time, I posted over at avsvorums about a problem I noticed trying to decode the DTS HD MA sound from the Obilivion blu ray. In short, the center channel becomes distorted in loud bits. Since that posting, I have realised that specifying '-core' option to eac3to fixes the problem but of course its not "lossless", which my decode of the MA track clearly isn't either in this case.
I have uploaded a sample .dtshd file from 8:10-8:20 of the film which exhibits the problem. Also included with the sample are my eac3to decodes of the centre channel with and without "-core" as well as the libav decode, which also exhibits the distiortion. And of course all the logs and eac3to -test results. I get the same results (bit-for-bit) using eac3to with the Arcsoft decoder versions 1.1.0.0, 1.1.0.7 and 1.1.0.8. I also hear the distortion when decoding the .dtshd directly in mplayer, vlc and audacity (which I think use the same code as libav anyway). EDIT: On second thought, the distortion is there in core track as well. I don't know how I didn't hear that before. Last edited by kevmitch; 17th August 2013 at 16:49. |
