DTS-HD to PCM conversion

Which tool can convert 5.1 DTS-HD to 2.0 PCM losless?

tebasuna51 · 25th July 2010, 10:14

Downmix 5.1 to 2.0 isn't lossless.

You need eac3to with ArcSoft DTS-HD decoder and run:

eac3to your.dtshd output.wav -downmix

the best way to keep the channels and lossles is FLAC.

eac3to your.dtshd output.flac

What to put in the command line that i have chapters?
I want to extract audio only out of m2ts from /BDMV/STREAM.

for a bluray:

eac3to 1) 1:chapter.txt

or

eac3to your.m2ts 1:chapter.txt

thats all.

Doesn't 5.1 downmix to 2.0 requires phase shift? Or is this necessary only for Dolby sources?

Never with Dolby sources.
With other sources we can't know. Maybe.
Try the two options and select the best for you.

ok. thats a bit of work

you demux the the sound with eac3to.
then you mux the wav with mkvmerge and use there the splitoption "after timecodes". you copy the timestamps from the chapter.txt.
you get the soundfiles and then you demux the mka-files to your.wav
