DVDs work because your DVD player expects DVDs to contain DTS and can deal with it. It refuses to believe a CD can contain anything other than redbook and will always attempt to play one as redbook, no matter what you tell it. (MP3 CDs are a different issue -- those are actually CD-ROMs and your player can figure that out. But DTS CDs look exactly like redbook CDs to your player.)

The only way to play those suckers back is to output PCM digital from your CD player and feed it into a DTS-aware receiver. The receiver has no idea it's getting the digital signal from a CD instead of a DVD and happily decodes it.


Nope. My lowly Cyberhome DVD player ($40) plays DTS CDs just fine. Well, at least the one I have.

Same with previewing in Nero. It attempts to decode a stereo 44.1/16 file (which it isn't, it's just masquerading as one). Hence, white noise.

Thanks Ryan.

Perhaps a stupid question, but would it be possible to decode correctly if I burned it onto a DVD-R?

Is there a special setting for them? How does it know they're DTS and not redbook?

Not sure. You'd actually need to author a DVD, not just burn the WAV file onto a disc. But it might work then, I don't know.

Possible sh.tv misinformation here, but I thought a DVD player would read the DTS CD as a DVD hence the reason why it would work.

I just tried using the 5.1 outs of my Panasonic S97 and it did, in fact, decode the disc correctly. It even flashed "DTS CD" on the display.

I suspect you need more practice working your telephone machine.

Maybe I need a firmware update? :D

Well, I'm going to try to burn it from the cue sheet and see what happens.

Tried to burn it from the cue sheet and got the following message from Nero:

An error occurred while loading the cue sheet file
C:\blah blah blah (my directory etc)
Line 3

Is there any way I can go in to the cue sheet and edit it? Or can I simply create another one?

You can easily edit the .cue sheet. They're just text files.

Ahoy hoy?

No idea how it works, but all I had to do was put the disc in and push play.

Update - After putting this FLAC headache aside for a few weeks due to technical issues and home improvement issues, I had some time this weekend to revisit the issue I had with DSOTM flac.

Ess Ay Cee Dee was kind enough to help work out a solution for this. After trying several different things (different FLAC decoders, audio specs on the DVD player, etc), I was about ready to throw in the towel when I tried one other option that neither of us had come up with yet: resetting the DVD player.

That was it! When I tried a second copy of the CD, the DTS logo was on the player's display (which didn't happen the first time around) and there was sound! At first, I was certain it still wasn't working but then realized that I only had my rears connected and it took a few more seconds for the effects to start. Now I can check out Parsons' mix and see which is better for myself.

Once again, thanks to SA for putting up with my emails and getting me up and running (insert Ed Bishop emoticon here).

Three and a half years later, and nearly a year after I found this program...

DTSdec does the trick. You can have it either mix down to stereo, or export a multichannel WAV file. I just decoded Let It Grow to a MC WAV, and sure enough in Audacity I get 6 tracks (albeit only 4 with any real information). So...success.

So DTS Releases on CD can encode and decode to digital out just as any other CD can right? And then the DAC in my amp can do it's 5.1 magic from there....?

I have all those Quad reel to reels as well, you know those fan conversions from tape to computer input to CD-R. Fun stuff!

As long as your amp handles DTS, yes.
