Yes. Even if (probably?) not with eac3to.
BeSweet supports it via a *.mux file (you can use BeLight as GUI to create that and feed it into BeSweet). Unfortunately, the quality of the AC3Enc plugin is quite bad, and many versions have been bugged regarding a too low volume. Also, Aften supports reading from six mono channel WAVs. WAV to AC3 Encoder is a useful GUI here. The Aften AC3 encoder is not yet close to commercial encoders, but still possibly the best current freeware AC3 encoder. WAV2AC3 uses Aften as stand-alone encoder; eac3to uses Aften as a library. Last edited by LigH; 6th September 2012 at 19:26. |

Yes, ffmpeg's AC3 encoder developed a bit since that AC3Enc plugin for BeSweet.
Interleaving the six channels to a 6-channel file may pass the 4 GB limit, therefore the W64 target is recommendable. The usual WAV header has only 32 bit size fields in their chunks. |

Question about RAW/PCM channel remapping. If I demux RAW/PCM from Blu-ray to RAW, eac3to swaps endian and remaps channels. If I later mux that RAW to Blu-ray M2TS with tsMuxeR, wouldn't I then have wrong channel order?
Oh, and second question if anyone here has some ideas. What would be the best way to join The Lord of The Rings EE main movies as those are on two discs? I would like to get those to mkv.

AAC to AC3 not working
I have a long 6-ch AAC file which I want to convert to a 6-ch AC3 file. The source file has been created by Nero AAC encoder, here is the MediaInfo analysis:

To decode AAC with eac3to you need Nero 7 decoder installed (like say first post in this thread).
You can use Foobar2000 or BeHappy-BassAudio to recode AAC -> AC3 directly. Or you can decode AAC to WAV (with Faad) and after use eac3to. You can't change the extension of the file. A .aac file is AAC audio with ADTS headers. A .m4a file (mp4 with only audio) is AAC audio in mp4 container.

Thanks tebasuna for your quick reply.

I have NeroAacDec in my eac3to folder though, and NeroAacDec can certainly decode my source file. Why in the world can't eac3to use NeroAacDec for decoding AAC files? Quote:

ffmpeg is fairly easy to use for this task:
ffmpeg -i input.m4a -ab 448k output.ac3 Sadly, eac3to cannot utilize neroaacdec.exe, nor can it handle AAC audio in mp4 container. (But ironically, it cannot create AAC audio without mp4 container...) |

Thanks sneaker_ger,
I know that ffmpeg can make these conversions. Frankly I am a little worried about the quality. Do current ffmpeg versions use Aften for AC3 encoding? I could not detect "libaften" anywhere in a couple of recent binaries. In the meantime I made my own little tool for AAC to AC3 conversions. It uses faad and Aften. Here is the readme: Quote:

Has anyone tried to compile new avcodec.dll and avutil-50.dll to use with eac3to? I'm not sure if there have been any big changes but the ones used by eac3to are over 2 years old now.

The changes made by madshi are there in the "legal stuff" folder, so it should be possible to build new libraries. I was just wondering whether anyone's tried that out yet.

I was using eac3to to convert the DTS-HD MA track to a 7.1 AAC (Arcsoft to Nero), and the audio would become progressively out of sync regardless of how I muxed it. I tried all manner of fiddling / manually specifying the video framerate, but nothing worked. In the end (2 days of slamming my head against a wall), I ended up going with 5.1 instead of 7.1 and everything worked fine. No idea what's up. Next job I do I'll post about it here if I have the same issue. |

Basically you have to cut off the last few seconds of the end of part 1, and about 1 second from the beginning of part 2. You can do this in mkvmerge. This is because the audio stream ends before the video stream. |

Now only hope that Madshi will soon release madVR 1.0 then he can return to develop eac3to.
