Sorry, bad choice of words... yes, wav file just hisses when playing in windvd, haven't tried with burned cd (those are all in the car) but I am burning more tonight so I'll test. Either way, if this turns out to be a flaw in the player, is there any chance enough people play dts cds that this would ever be fixed?

Lore

I think I made a mistake about the files -- if it just hisses it may be that WinDVD can't actually play the .WAV files as DTS files and you have to burn them to CD first (per svtmike's posting and my follow-up)

Salden

I read on WinDVD's site that only windvd platnium can decode dts. Funny, I have a version that came with my motherboard and has the dts logo right on the gui but no dts decode? Odd...

svtmike

That is true; I've got the Platinum so the decode works fine on my system.

Is it possible to take normal songs and put them on a DVD-A, and have TL recognize it?

So instead of 15-20 songs per cd, u can get about a 100 ?

Not without DiscWelder or a comparable program.

I'm convinced now that the noise (imagine a nail scratching against glass for an instant) is a result of the dts decoder in the TL. It is probably poor or non-existent error correction as svtmike suggested. After almost 2 hours of cumulative listening on my home system I heard zero noise spikes. The average interval between noise on the TL using the same CD was 1-2 minutes.

Lore

And the poor error correction _could_ be chalked up to bad media (at least bad media in the sense that the TL doesn't like it)... so try a different CD brand and see if the same .WAV files cause screeches.

I had a few screeches on one of the CDs I made which never came back after the first time. I guess it just didn't read it right that one time.

svtmike

I've found differing performance even among CD-R's of the same brand. I've tried slowing the burn speed down to 4x, none of it has made a difference for me.

Homemade DVD-A's on the other hand work great.

Salden

Right Mike, regarding dts cd, I don't think it has anything to do with the media or burn speed. I think it's all about the encoder. Can we try this with something besides surcode?

svtmike

I still think it's the error correction.

I made two different copies of my Henley disc onto CD-R media of the same type. The noise occurs at different places on each.

Mike

creamy-nuts

man i cant even find SurCode, or even DiscWelder.

svtmike

You won't find DiscWelder unless you buy it. Minnetonka has software dealers that sell it for less than list; I got mine from www.audiomidi.com.

BTW - I emailed Minnetonka yesterday about the status of Discwelder Bronze and they said it will be available LATE March.

would any of you guys who have all the equipment and can do this successfully be interested in making a few bucks? I have some dvd concerts i'd love to have on dvda, but can't afford all the equipment. I don't know how exactly we can do it, but if you're interested send me a message and maybe we can work something out.

My understanding of DTS WAVs are that they are WAV files encoded using the DTS algorithm. As such, why is it not possible to burn that onto a DVD-A? Isn't the WAV still a 44.1 khz 16-bit file? Won't the TL be able to decode it?

Or is it because when playing creating the DVD-A, even the cd quality WAV files are "expanded" to 5 channels (2 channels of music, 3 channels of silence) -- I'm a little confused.

svtmike

DTS .WAVs are exactly what you say - WAV files encoded using the DTS algorithm. The only way to burn that onto DVD-A is to decode the DTS .WAV first into five monophonic .WAV files, and then put those onto DVD-A.

The DVD-A spec only supports two types of coding of the bitstream it reads off of the DVD - LPCM and MLP Lossless Compression, which just decompresses on the fly into LPCM. DVD-Audio players do not support the detection and decoding of a DTS bitstream off of a DVD-A disc as a result.

There is a standard level matrix for "downmixing", or playing 5.1 sound through stereo speakers. There is probably a corresponding level for "upmixing" a stereo signal through a 5.1 setup, to ensure that the subwoofer level is proper when the L/R channels are split across the front/rear speakers.

The TL can decode DTS .WAV files, but only if they are burned onto a CD in redbook audio format.

Thank you for your very detailed response. Hopefully USPS Priority Mail will come through and deliver my goodies tomorrow so I can mess with it. I played around with the demo and am not too excited about the interface but I can live.

sfintel

I don't think you are correct here. I have a DTS encoded DVD-A (Porcupine Tree In Absentia) that is proof. See http://www.dtsentertainment.com/dvdaudio.php for a listing of DTS DVD-A's.

HEY SOOPA!!!

Can we make this a sticky or post it at the top of an ICE forum? This is looking like something that will come up again, and again and again and, well, you know.

frozenpenguin and svtmike - thanks a bunch for all of your help on this topic. I look forward to trying this when i finally get mine.

Has anyone here tried to convert an SACD to DVD-A or a DTS-CD? The slection of DVD-A discs isn't that great yet, but my local Best Buy seems to have a much bigger selection of SACD.

Also, when using discwelder (which I just ordered...waiting for delivery) to make a DVD-A using 6 wav files, does this mean that the total capacity of the disc is about 90min? A dvd holds about 6.7 times that of a CD, but there are 6 channels, so it balances out, right?

Thanks,

Jason

Hey guys,

There is a whole underground community of folks who do DTS conversions of old '70s quad recordings. The guy who started it all has over 400 titles available. You can check his list out at:

http://hometown.aol.com/matrixquad/list.htm

There is also a community www.quadraphonicquad.com that has a forum (which you have to join to access - no charge - no fee) with a seperate section on DTS CDs and DTS conversions, as well as a DVD-A section with info on upcoming releases and reviews of players and software.

BTW - The Acura TL is the official car of QuadraphonicQuad!!

If you are into this stuff, it's worth checking out.

Those are DVD-A's by DTS Entertainment. I even have a couple of them (Queen's The Game and A Night at the Opera).

Those discs (the Queen discs I have, not the entire DTS Entertainment catalog) feature 96kHz/24 bit DTS encoded tracks in the DVD-V portion of the disc, but the DVD-A portion is Advanced Resolution MLP encoded.

Mike

sfintel

I just had another look and you are correct. There is a 5.1 (24/48) MLP encoded group as well as a 5.1 (24/48) DTS and 2-channel groups.

TLover

If anyone is willing to convert some concert DVDs into DTS-encoded discs I'll glad pay for your services.
