Even with the complete Audio Plugins, DSFilter, and Lib folders restored, it is still not working with eac3to 3.06-3.11. Perhaps another DSFilter ax needs registering or there is some other registry entry missing? I see what you mean about that period where it behaved differently: 2.87 is the oldest version I still have which works on my system (so, presumably at least 2.87-3.05) while 2.80 does not.

I had to exclude file extensions, my media drives and the working directories I use for video conversions/muxing. |

Hi madshi, I tried that -simple switch as you suggested. It works, however, I found out that the WAV files produced with that option are not bit-to-bit identical (data chunk wise). How is that possible? Here are my sample files, which I used for the test. I'd really appreciate if somebody else could test it also and post his report on different/identical AC3->WAV results.
Command lines invoked -> Modern WAV output (WAVE_FORMAT_EXTENSIBLE) Code:
T:\eac3to\eac3to.exe "test.VOB" "R:\test.wav" -down16 -libav Code:
T:\eac3to\eac3to.exe "test.VOB" "R:\simple.wav" -down16 -libav -simple In general, they differ a LOT, the samples do not match although they should because they were produced from the same source, by using the same tool and same decoder library. How come they're not identical is beyond my comprehension. When I imagine all the guys who struggle to get LOSSLESS audio from their TrueHD/DTS-MA and so on while there seem to be weird issues even with ordinary stereo AC3... |

In the past people only had problems if they tried getting around installing full Nero 7 and/or if they tried to use stolen license keys. I can't - and don't want to - help doing either of that. Now of course I don't know if you have installed full Nero 7 and if you have proper license keys. If you haven't, please don't ask me for help. If you have, I'm sorry about the problem you have, but I don't really know how to help, since everything works just fine on my PC. Quote:

Ask eac3to to convert the "-simple" wav file to extensible by doing "eac3to simple.wav full.wav". And ask eac3to to convert the extensible wav file to simple by doing "eac3to extensible.wav simplified.wav -simple". Then compare "simple.wav" with "simplified.wav" and compare "full.wav" with "extensible.wav" and you should notice that both comparisons are 100% bit identical. There are no weird issues. Your testing method is invalid. |

You can use my test.VOB file for your tests. My system specs: Athlon 64 X2 4200+, Windows XP SP2 32-bit Desperately waiting for any possible explanation of this abnormal behaviour... |

It's not a bug, it's a feature.
madshi uses random noise dithering for downsampling (instead of a fixed noise pattern in previous 2.x or 1.x versions). Actually, you have successfully proved that the random number generator of eac3to works correctly. |

I tried omit -down16 option as to avoid downconverting. Resulting WAVs (24-bit) are still not consistent. Isn't AC3 internally only 24-bit also? I thought lossy format means some info is lost during encoding, not generated randomly on each decoding. |

BTW, "consistent" is actually bad when talking about reducing audio bitdepth. |

Hi madshi!
is possible to specify what track to extract ? the -demux seems to extract all.. i would like to extract only audio, or subs, or specific stream/track thanks! BHH

Ok, some algorithms use fixed noise patterns or calculate the noise the same way every time. With such algorithms you will get identical results if you repeat the same processing steps multiple times. But truely random noise is different every time. So being "inconsistent" is exactly the way to go - - but only when reducing audio bitdepth, of course. |
