Is it possible to get the runtime from those DTS bytes? I mean could I just search in the file for the first and last sync word, substract the DTS values and convert them to a runtime somehow? That would be nice. Right now I don't have any at hand. But I'm sure I'll run across them again sooner or later. Will PM you then. |

.raw input
it seems weird that .raw is not a valid input extension since eac3to decodes to just that. renaming it to .pcm works but then eac3to seems to assume it's a blu-ray lpcm track and wants to remap the channels.
i wanted to use -down6 on a raw file that was decoded from flac, but i just couldn't get it to work.. 'eac3to bla.pcm bla.flac -8 -down6' makes a 6ch flac but channels are mapped wrong 'eac3to bla.pcm bla.flac -8 -0,1,2,3,4,5,6,7 -down6' makes an 8ch flac flac to flac with -down6 doesn't work either.. 'eac3to bla.flac bla2.flac -down6' creates an 8ch file it of course works just fine with the orig blu-ray lpcm track but not anymore once the channels have been remapped. also .wav input seems to be broken.. even wavs made by eac3to give the error message "The raw file has 0 channels, which is not supported by eac3to." |

eac3to v2.0 released
http://madshi.net/eac3to.zip Please see first post of this thread for the full help text of the new version. Here I'll post a list of the changes instead: Code:
totally new features * AC3 decoding support (Nero's decoder without DRC/dialnorm) * resampling to 44.1/48/96 kHz (by using "r8brain") * apply/reverse PAL speedup (by using "r8brain") * "eac3to sourceFile" will print out source file details strongly enhanced features * dramatically improved performance (no intermediate files, anymore!) * proper 6.1/7.1 downmixing to 5.1 instead of just dropping the back surround channels * RAW/PCM file detection now auto detects channels, bitdepth and endian * WAV is now fully supported as source file format * destination file extension "PCM" creates Blu-Ray style LPCM tracks * bitdepth can be reduced to anything between 14 bits and 23 bits DTS related improvements/changes * DTS-96/24 support added * "open bitrate" support added * strange channel configuration support added * removal of zero padding from DTS files added * eac3to can fix broken DTS-ES files (they decode to 5.1 instead of 6.1 without the fix) * dialog normalization can be removed without removing the additional DTS-HD data now * core extraction must be specifically asked for now (see "-core" switch) AC3 related improvements * did I mention that eac3to can decode AC3 now? * strange channel configuration support added TrueHD related improvements * delay problem (hopefully) solved * fixed: sometimes some audio data in the middle of a track was lost * TrueHD/AC3 interweaved file can be stripped to TrueHD only now various minor improvements/changes * progress bar added * eac3to detects file format independently of file extension * multiple input files can be treated as one big file * "sox" is not needed, anymore * "dump" filter not needed, anymore * "aften.exe" replaced by "libAften.dll" * "flac.exe" replaced by "libFlac.dll" * DTS/DD+/AC3 source filter ships with eac3to now * 8bit support added * various bug fixes Just to be sure, here's the previous eac3to v1.23 for download: http://madshi.net/eac3to.v1.23.zip Last edited by madshi; 18th November 2007 at 00:10. |

Thanks madshi, I just started playing w/eac3to today, and here pops your post! Like the sourcefile printout, and already noticed it prints my "Nero missing" error instantly this time!
I see that Nero 7 is dirt-cheap, and the plugins are $25; but I have not used Nero for years as it's bloated with stuff I neither need nor want on my computer. Has anyone here figured-out how to minimally install the audio decoder from Nero 7, and the Plugins without all that other junk, er, good stuff? |

i will remux letters from iwo jima again later tonight, will be able to say then if that truehd delay thing is fixed now
btw. could you please explain what this means: * destination file extension "PCM" creates Blu-Ray style LPCM tracks ? when I want to convert blue-ray movie LPCM tracks to flac, do I still have to rename the tracks to .pcm before I put them into eac3to, or to .lpcm or doesnt it matter which of both?

The new RAW/PCM detection algorithm costs some time. So I'm using it only if the file extension is "raw" or if there's a "PCM" somewhere in the file name. Not sure but IIRC xport puts a "PCM" in the file name? If it does, you can just convert the file without having to rename it. Otherwise rename it to "*.pcm" or "*.raw". That's not too hard - is it!? |

you didnt get my question at all, I asked if have to rename the file to .pcm or .lpcm for blue-ray flac tracks, since the the source input option now is (L)PCM and not only .pcm as in previous versions.
found out it actually doesnt matter. |

I have to make an announcement: MADSHI IS A GREAT LIER!!!
...and i explain: 1. He was telling that new eac3to won't be ready till next week, 2. that he hadn't make any progress to AC3 decoding, 3. that PAL<--> NTSC conversion won't be ready for the next version. 3 big lies Thank you very much!!! |

No honestly, I didn't really expect AC3 decoding and PAL<->NTSC in the first version. The reason why AC3 decoding made it into this version is very simple: I noticed that my E-AC3 Nero related hacks worked for AC3, too, without any changes. So it was really easy to add AC3 decoding. |

fantastic. i don't know how i could live without this tool and now it's a tenfold better..
you're my hero. by the way, i'm guessing noise-shaping is used with the TPDF dithering? any idea how the quality is compared to ssrc/wavewizard? really interested to see what kind of results 24->20bit conversion will bring.. |

C:\Tools>eac3to ice.greek.ac3 ice.greek.new.ac3 -slowdown -resampleto48000
AC3, 5.1 channels, 1:26:53, 384kbit/s, 48khz Creating/writing file "ice.greek.new.ac3"... Done. Tried something different this time. The process finished almost in no time and the output file is identical to the source. Did i do something wrong? |
