PCM 7.1 channels encoding

[Altaria]

hi

how can I encode PCM 7.1 channels (Ghost in the shell 2) to another format, like flac, without losses
i have extract them with eac3to, but I'm not sure whether eac3to can handle this.



and how can I load this video (MPEG 2 HD) in megui, can I use DGDecode_mpegsource?, or should i try graphedit with a special filter

thanks

Yes it can.
You don't even need to extract.

Use "eac3to.exe sourcefile.xxx -check"

Then "eac3to.exe sourcefile.xxx tracknumber: destinationfile.flac"

No, you need a program that can mux files.
Depending on your needs, you could try, tsmuxer, mkvmerge etc.

Use DGMPGDec.

thanks,

well i have joined the video (and audio with eac3to) files with avisynth unaligned splice for video only, ich hope it is synchron to the audio

Yes, it's synchron but it looks like the 7.1 track is damaged, because
eac3to : "The source file looks to be damaged (discontinuity)"

When I rip the PCM track to flac it looks like the speech is sometimes very low, how can this be?, I also try "-normalize" in eac3to
