With 16 bit in 24 bit Lossless audio conversion is there any way to skip the first pass if I already know what's inside, or at least do the first pass without encoding and a forced second pass? I was thinking maybe -down16 but then realised that would just turn the 24 bit track with 8 bits of zeros into a 16 bit track with 5 bits of zeros. Or is there any way to just reverse the process, start with 16 bit and if it encounters a 24 bit section restart at 24, if it winds up being 20 bit it can do a third pass and I can sit there feeling stupid.

However, when you don't know what's inside, I know of no way to just restart encoding with 24-bit, you'll have to make do with 24-bit and reduce that to 16t-bit if eac3to later detects that the whole track is only 16-bit... Last edited by DarkSpace; 2nd June 2014 at 16:18. |

Is there anywhere that states all the available switches?
The wiki doesn't list "-dontDither", nor does anything when running eac3to. http://en.wikibooks.org/wiki/Eac3to/How_to_Use#Command_Line_Syntax

Probably something close to the following string dump:

Someone already collected all documented and undocumented switches a while ago:

Not that I'm aware of, actually I asked as a feature request on the MakeMKV forum if the program could give a report at the end as to whether a 24 bit DTS-MA or TrueHD track turned out to be 16 bit or not during FLAC conversion. If that happens EAC3To going through both passes during the re-encode would be a waste of time. But of course Mike doesn't usually implement anything so it's unlikely to happen, which is why I had to find a way to justify getting the answer I got.

I converted a 24/44.1 6-channel DTS file to a FLAC using eac3to with Arcsoft DTS Decoder. The conversion went fine, but there's something weird: I played both files with foobar2000 and checked the waveforms with the Waveform Seekbar addon.
DTS: FLAC: The LFE channel (on the bottom) is louder on the FLAC. Why is that so? |

...and a REAL problem. There's a certain DTS-CD whose DTS-ES files I could extract properly with bsconvert, but once I put them in eac3to, it simply refuses to decode them with Arcsoft. It doesn't even produce an error. It just says:
DTS-ES, 6.1 channels, 0:04:58, 1235kbps, 44.1kHz Remapping channels... Decoding with ArcSoft DTS Decoder... And that's it. Other DTS-ES files I've used work perfectly. I use Arcsoft 1.1.0.0. |

I asked a question about thd+ac3 in another topic ;
http://forum.doom9.org/showthread.ph...42#post1685842 I copy it here, the eac3to topic is more appropriate ; is there a trick to mux a True HD track with an ac3 track (both having exactly the same duration) into a single .thd+ac3 file or this interleaved file can only be created from a single True HD track ? It's just by curiosity, I understand that it's not very useful because if one really need to have another ac3 track (than the True HD track), it can be muxed into m2ts in addition to the .thd+ac3. The only utility I see would be to avoid to increase the total bitrate (of a Blu-ray for example) if one need an ac3 track with a different mix than the True HD track. I guess it is possible (but is maybe not available yet but could perhaps be added in eac3to), because just after having created the ac3 track from the True HD, thus just before interleaving them, there are 2 tracks. And I don't see the difference between taking this ac3 stream (existing as a temporary file) and another (already existing) for the interleaving operation. |

Please upload a sample (dtswav) before extract with bsconvert.

Nope, now you can create a thd+ac3 track with the ac3 created for eac3to with the thd input.

I don't know if madshi can add this option.

Ok, and do you know how the interleaved ac3/True HD tracks are created by professional tools for Blu-ray's ?
Because I guess that unlike eac3to, they don't create an ac3 stream from the THD stream, they probably take 2 streams (even when they come from the same mix) and interleave them. |

I don't need to get the core (eac3to can do it and also TSMuxer IIRC), I'd like to know if an ac3 stream and a THD stream without core can be muxed together to get a .thd+ac3 (which is usually done by re-creating the core from a THD track whose core has been removed).
