From your posted MediaInfo, I think it says TrueHD track is mono and embeded AC-3 track is stereo, not that the audio track has 3 channels. I may be wrong though. Maybe you should upload a sample.

Could somebody tell me how you get eac3to to detect sonic audio decoder without installing it? I can get Nero, arcsoft v6, and surcode all detected without installing the entire parent program but I am unable to do the same with sonic audio decoder.

On the change / improvement request front... It would be nice if eac3to reported durations out to the ms instead of the rounding to the second.
So instead of this: AC3, 5.1 channels, 0:19:18, 384kbps, 48kHz Decoding with libav/ffmpeg... Reducing depth from 64 to 24 bits... Writing W64... You'd get: AC3, 5.1 channels, 0:19:17.824, 384kbps, 48kHz Decoding with libav/ffmpeg... Reducing depth from 64 to 24 bits... Writing W64... |

So. You have an audio-only Blu-ray, or a concert Blu-ray, and you want to rip the audio onto your computer, perhaps into nicely track-separated FLAC files.
Ripping is the easy part. Problem is, eac3to gives you a single audio file and a chapters file, but you still have to chop that big file into bits following the timestamps in the chapters file. How I do it, is I turn the chapters file into a CUE file, which I then feed to foobar2000, which generates individual audio files following that CUE sheet. But making the CUE file is a pain in the backside, so I decided to write a little Python script that does it for me. https://github.com/frederik-vaassen/...ter/makeCUE.py All this does, basically, is read in the chapters file, extract the titles (if available) and the timestamps, and pour them back into a properly (I hope) formatted CUE file. I made this purely for myself, and as such it's basic and probably won't work on everything, but if you run into errors, feel free to DM me and I'll try and have a look. You will need a recent version of Python 2 (I use 2.7). Place the script in the folder your files are in (you can also specify the full path of each input and output file as arguments) and do this at the command line: Quote:
Hope this is of use to someone! |

I merge the m2ts (or the audio file extracted with eac3to) into an MKV or MKA (no need for the video track) with chapters (extracted with Chapter Grabber) for that.
Then open that MKV/MKA into foobar, it'll rip and split everything into separate audio files. Last edited by Lenmaer; 6th January 2014 at 13:15. |

Hey guys real quick question: If I decode 5.1/7.1 audio to 2-channel Dolby Pro Logic II using the -downDpl switch, plus the -mixlfe to mix in the LFE channel, am I doubling the .1 bass track, or does EAC3to ignore the -mixlfe switch when using the -downDpl switch? I would not want to mix in LFE if the -downDpl switch already does this...
Thanks! |

I think I remember a "no" on this question which was discussed before, somewhere; DPL (II) does not care about LFE without explicitly mixing it in, the downmix matrix only includes full frequency channels.
No guarantee, though. __ From my previous experience in a DVD production studio (many years ago), I remember: Movie studio made audio streams with LFE channel should usually not have simply the filtered low frequency part of the whole spectrum which is then probably missing in all other channels. Instead, this channel usually has, as the name describes, additional and optional "Low Frequency Effects", and the full frequency channels would usually still contain low frequencies of movie set recorded audio. No guarantee, either. Last edited by LigH; 10th January 2014 at 20:37. |

I'm just wondering what the generally accepted pronunciation for EAC3TO is, I tend to just shorten it to Ecto in my head but I mentioned the program in a verbal conversation recently and realised I'm not sure what I said was correct.

That's how I say it when I'm typing it but it's a bit of a mouthful. As far as I'm aware that was the first time I've ever included the program in a conversation, when experts are discussing it do they shorten it to anything in particular or am I a bit of a yokel?

Far be it from little old me to argue with you but I'm pretty sure if you had to include VS2013x in an explanation multiple times you'd shorten it to 'Visual Studio', or if multiple versions of VS were mentioned there's 'Express' or '2013 Express'. But to say EAC3TO repeatedly would get kind of wearing, not to mention the fact that Visual Studio kind of flows whereas EAC3TO is full of hard starts and stops and would be completely meaningless to anyone not fully engaged in the audio encoding community. Do people really keep saying E-A-C-3-2 repeatedly or does the program exist in a realm where the name rarely has to pass through human vocal chords?
(by the way, I love the way you really need to know something about video/audio encoding to even be permitted to post on this forum!) |
