DTS 9624 decoding

[51preference]

Is there a way to decode dts9624 into 24 bit 96 KHz wavs?
I have no problem decoding the 'normal' dts core part, but how to
really decode
the extra 9624 information?

Has anyone done this...what tools were used?

Thanks!

DVD Audio Extractor will do that in Direct Stream Demux mode.

[Neil Wilkes]

With full 96KHz resolution?
Cool.
Previously, I only knew about the command line tool - DTSDec.exe
(Usage is simple. Put the exe file somewhere easy to remember. Root of
the C drive, for example.
Syntax is as follows:
Load a DOS command editor, and get the prompt to the C drive.
DTSDec.exe (path to filename) -m1 (for mono files, leave out for
stereo)
So a full example might be as follows (given DTSDec.exe on the root of
the C drive, and a .dts audio file (or a .cpt one) in C:/Audio Files
DTSDec.exe C:/Audio Files/surroundmix.dts -m1
That will take the file "surroundmix.dts" and extract it into 6 mono
WAV files.

DVD Audio Extractor looks a lot easier though - thanks for the
pointer.
Wonder if it works on DTS-HD files (extension .dtshd)

[gshannon]

Yes. I was curious when I saw this question. Took a Genesis 96/24 disc
(Foxtrot) and extracted the DTS files. Recompiled into a DVD with DVD
Lab Pro and the player showed I was back to 96/24. Didn't know that
would work until I tested it.

Thanks for your efforts, but:
"DVD Audio Extractor will do that in Direct Stream Demux mode" will
create a *.dts file, but I want the dts information fully decoded in a
multichannel wav.
It is able to create PCM/WAV, but output will be maxed at 24/48,
meaning the extra bits are ignored.

dtsdec is cool, but seems to suffer from the same lack of seeing the
extra bits
dtsdec -o wavall > some.wav file.dts
creates a 32/48 wav

So both solutions decode, but only the core dts part, not additional
one that make the difference between
DTS and DTS9624.

More ideas?

Thanks!

[gshannon]

Right. I was so surprised to get the 9624 dts files from a DVD using
DVD Audio Extractor that I forgot you wanted them as wavs. Sorry.

[elshagon]

I think TranzcodeGui is limited to 48khz wav's also. One idea is if
the audio is originally from a dvd-audio you could use DVD-A Explorer
and extract the 96/24 wav's that way.

[Joe A]

I'm interested in a solution for this too (Genesis - Invisible Touch
and Depeche Mode - Violator, both are DVD-V with DTS 96-24). I also
can't get better than the 48/24 core.

DVD Audio Extractor doesn't even recognize the track in Violator.

I do have the .DTS tracks extracted for Invisible Touch, and it does
go to the receiver as 96-24 correctly. So I'm stuck, like you, on
finding something to give me 96/24 wave files out.

[elshagon]

could you re-author the 96/24 as a dvd-a and then use dvd-a explorer
to extract the wav's?

[jolson]

Why do you want your files to be much bigger, with the same quality
(at best) as before?

[Joe A]

It's pretty simple, really.

- We don't want our collections to be of 35 different formats, we want
a "lingua franca" so to speak.
- You can't put metadata tags (artist, album, et al) into a .DTS file
- So far every software player I've seen other than DVD players
(PowerDVD, etc.) only output the core 48/16 from the DTS files.

[gshannon]

Could you play the DTS 9624 file and record it into your PC at 9624
wav? From there you would master the DVDA. This introduces an analog
stage but since you're going from lossy to lossless that shouldn't
have much of an effect.

I d'nt remember but a avi-encoder soft decode dts 96/24 from dvd in
direct stream...
I search de name of software if you like it.
Sorry by the english :-)

[Joe A]

Yes, if you can think of it, we could use it. Thank you for your
help.

I believe Hypercube Transcoder ( http://www.videohelp.com/tools/Hypercube_Transcoder
) can convert DTS 96/24 to WAV (either one 6-channel WAV or 6 mono,
don't remember).

However, I believe it uses filters from PowerDVD, so that needs to be
installed. I think you also need a 96/24 capable soundcard, since the
filters will mandatory automatically downsample if it sees that the
soundcard can't handle 96/24...

Unfortunately not. It has WAV output upto 48KHz, at least the 3.05
version I tested.

The reason I want this is indeed to convert my dts collection at the
best possible quality
into multichannel WMA. Main reason is htpc playback thru a single
connection (hdmi)
with proper tagging and replaygain.
I guess I have to stick to the core stream...

Well, maybe music fan will remember the name of his tool...

Thanks so far...

[jolson]

The H-T author said it should, with the right version of PowerDVD
(that doesn't downsample) and a 96/24 capable soundcard...

You could always check if foo_input_dts (Foobar component) can decode
96/24, then you would have Case Closed...

[51preference]

I'm using foobar as we speak, and it doesn't decode other than 48 KHz.
There's 3 dts decodr versions for foobar, none does 9624.

There's many versions of pdvd floatin around, any idea which will do?

Well, I can't think that eac3to will fail - it does just about
everything. Don't know why I didn't think of it first:

Here's the thread: http://forum.doom9.org/showthread.php?t=125966

It also tells you which software you need installed so eac3to can use
the filters from it. That link says that PowerDVD now always is 16-
bit.

[51preference]

jolson, you da man!

eac3to does work well, 9624 properly decoded.

Thanks everyone!

[Joe A]

Yup, you nailed it for the ones I had a problem with too...

I did try earlier pointing eac3to to the DVD structure (which it
didn't like), but feeding it the extracted DTS files with the Arcsoft
dshow components worked like a charm.

Thanks everybody!
