hello I want to downmix a song from the credits of a mkv movie file.
Soundstream is 1,5 mBit DTS 5.1 with 24 bits. I splitted the credits with mkvtoolnix. Code:
eac3to e:\moviecredits.mkv e:\credits.flac -down2 -mixlfe eac3to e:\moviecredits.mkv e:\credits.flac -down2 eac3to e:\moviecredits.mkv e:\credits.flac Problem is that the classical song of the credits is ok, but when the song from the artist begins the sound is totally centered on the left. I tried with the 3 parameters. I don not habe arcsoft dts so that "libav" was used. |

Back to getting the best decoders for use with eac3to under Windows 7 x64...I can confirm the earlier posts that eac3to can work with the the TMT 2.0 codecs on Windows 7 x64 RTM. My PC originally had eac3to working with Nero 7 and TMT under winXP. I copied the required files from my winXP installation into the eac3to directory and used the Regserv32 command under Windows 7 x64.
All is good for DTS-MA using TMT. However, for the life of me, I can not get Nero 7 decoders to install. Despite successfully installing in my winXP, and activating with by BD/HD-DVD plugin, I can not repeat that under Win7. I've installed Nero as admin and normally, I've activiated the plug-in. But Showtime doesn't work (errors saying can't build graph on any content - DVD blu HD - and doesn't seem to recognize that BD is active since it doesn't have the BD enabled skin). Anyone have success with Nero 7 win 7 x64 and care to share how you accomplished that feat? |

I've already ripped my HD-DVDs when my machine was vista now that it's 7 and I'll probably never rip any quantity of HD-DVDs again I'll live with libavcodec. |

^DD+ 7.1 audio is virtually non-existent. HD-DVD's never used it and Blu-Ray never will have it since the discs can hold up to 50gb. 7.1 audio typically uses True-HD or DTS-HD.

The libav E-AC3 codec does support 7.1, so that is not the problem. The concern is whether the decoder (which is still quite new) works correctly. Apparently it produces different output than the Nero codec (which is Dolby certified). Also take a look at this thread:

I have retail version of Arcsoft TMT 2.0 installed on Win7 (with latest patch/update), added the bin path the path Environment Variable, but it still says that it is not installed when running the -test command....any ideas?

http://forum.doom9.org/showthread.ph...04#post1313704 AFAIK, there are no 7.1 EAC3 Blu-Rays or HD-DVD's. Discs that use 7.1 are usually Dolby True-HD or DTS-HD.

I always extract the best audio track to wav (better source material, better encoding result), unfortunately some Scandinavian Blu-rays only offer the standard AC-3 track (The Departed for instance). I noticed I was getting some large wav files from those tracks (compared to TrueHD tracks).
I'm not very confident in the Scandinavian publisher, besides lacking quality audio tracks on Blu-rays, The Dark Knight has a separate AC-3 track that is exactly the same as the embedded AC-3 track. Code:
The Dark Knight 3: AC3, English, 5.1 channels, 640kbps, 48khz 4: TrueHD/AC3, English, 5.1 channels, 48khz (embedded: AC3, 5.1 channels, 640kbps, 48khz) Code:
[a03] Extracting audio track number 3... [a03] Decoding with DirectShow (Nero Audio Decoder 2)... [a03] DirectShow reports 5.1 channels, 24 bits, 48khz [a03] Writing WAV... -------------------------------------------------------------- [a04] Extracting audio track number 4... [a04] Extracting TrueHD stream... [a04] Decoding with libav/ffmpeg... [a04] Writing WAV... -------------------------------------------------------------- AC3.wav - 6912 kbps 7,34 GB TrueHD.wav - 4608 kbps 4,89 GB |

This TrueHD track seems have 16 bitdepth (audio samples with 16 bits), when decode from compressed audio you obtain 24 bitdepth then the size is 24/16 = 1,5 greater. Of course the TrueHD.wav is the exact source audio.

I have demuxed my Harry Potter 3 HD DVD with eac3to and got a TrueHD track with a delay of 2002ms.
I got a file named: "feature_1 - 4 - TrueHD, 5.1 channels, 48khz DELAY 2002ms.thd". As a next step I wanted to transcode this file with eac3to into dts (using SurCode). From what I understand eac3to first decodes this TrueHD track into several WAVE tracks and feeds them to the Surcode Encoder afterwards. Is there a way to get rid of this delay during this process? |

However, as you're converting to DTS anyway why not go straight from the source EVOs to DTS, instead of demuxing the TrueHD track first? If you transcode then eac3to will apply the delay as needed. |

Because Nero AC3 Decoder does not allow to process more than one track at a time. That's why I first demux all the tracks I need (usually 2 E-AC3 tracks at least + TruHD) and process them afterwards.
