Does anyone know how to connect the DTS 35mm reader to any player or computer?

Hello friends, I have several DTS discs in several languages ​​of the same movie, I have verified that the id number of the movie is different in each language, so you can not play a disc with a movie from another country.
I use foobar2000 to play the aud files and see the id number.

Does anyone know how to change the id number of the aud files in order to use the audio dts in a movie from another country?

Yes, there is a foobar2000 plugin on sourceforge - it seems it can deal with 'encrypted' DTS discs as well. I don't know wether it's advisable to keep this low profile. I guess no one is using it for pirating, so, it's more for 'academical purposes' anyway...

Any opinion on that, Daniel?

Well, I no longer speak officially for anyone involved, but as observed upthread, the old DTS theatrical format is now supported thirdhand by Inventure Studios (who have licensed the technology from Datasat, who acquired it back when they bought the DTS Digital Cinema division from DTS). I think it's all sufficiently removed from today's reality of Digital Cinema and most content being watched via streaming services anyway that no one's getting bent about someone hacking the old DTS disc encryption.

As to the *why* - Brad is probably correct when he observes it's in many cases the only way to listen to the original theatrical mix in a home theater. I don't share his antipathy towards near field remixes; YMMV.

If you are ever in the position of being able to directly compare a 35mm print with DTS, SRD or SDDS against a bluray near field remix, you will totally understand why the near field remixes are total garbage.

It's home video, and these discs are simply not made for people who play them on high-end cinema-type audio systems, but for mainstream flat screen tv sets and soundbars, and it does make sense to adjust them for these typical playback conditions, it's a question of majority. Same as the colorspace for Bluray is reduced to rec.709 and not P3.

Yes, it would probably be best to put the nearfield mix on DVDs and Blurays as the default/first audio track in AC3, and add the original theatrical mix as e.g. dts HD. No one concerned about playback performance would care to be forced into switching over or to buy dts HD or TrueHD capable equipment.

My intention is not to put the DTS audio on a bluray or DVD, I have a Kinoton FP30D equipped with a DTS reader, I have a DTS XD10 and a DTS-6D, I have 35mm movies from other countries (Russian, English) and I would like I can put the audio in Spanish, I have some DTS discs of my movies in English and I would like to be able to change the audios of this album to Spanish in some way, since the DTS discs in Spanish I can not find them anywhere. This is why I ask if someone knows how to put audio files in some processor of these, I have the wav removed from the bluray and I would like to hear them at the same time I project my 35mm movie. This is why someone knows how to pass wav to aud, and if someone knows how to connect the DTS reader to a player or PC.

In this case you can get a piece of software (see below) that will allow you to sync playback to a bi-phase signal/SMPTE time code, or a physical player (TASCAM made a model of CD player that did this) and a bi-phase encoder and time code generator.

See here for info on bi-phase rotary encoders

The caveat is that if the source material and the print do not match frame for frame then you will lose sync. Any splices or film breaks that result in lost frames will also cause a loss of sync.

Use the encoder coupled to your projector to drive the time code generator and use your audio in whatever format your software or hardware uses. In this case not only is DTS unnecessary but it will be an impediment to what you are trying to accomplish.

It looks like there is a peice of software available that will take in a bi-phase signal, generate timecode, and play a media file back to that time code. I have not used this application so YMMV;

To add to this comment: Sadly, the public that plays these garbage field remixes of the feature on a continual basis in their homes, then comes to our locations to witness what we present on the screen, makes the decision to complain that our sound isn't the best, and even isn't the same as their systems at their homes.

We've even received recommendations that they the people who did their hone installs, make a visit to our location to see what can be done to improve the sound that these, the public are hearing so it can match the garbage they're hearing at their homes.

Yet, it's fun in a way, to educate them that we were first in this multichannel cinema sound and doing it as its supposed to be.

The near-field mixes that Disney have put out lately have been absolute trash.

what is a near-field mix?

Basically a near field mix if one that has been "dumbed" down at a much lower volume level for home speakers with the goal of keeping the dialogue at a level that is easy to hear. As one remixer put it...."so you can talk on the phone and still hear the dialogue without all the other noise......"
Go figure

If you have a hex editor you can change the serial number and reel number of each file. The first 92 bytes are a header.

Location 78 or 0x4E is the reel number
Location 80 and 81 (0x50 and 0x51) are the serial number

Hope that helps.

Markus

ahah, Markus, I wasn't the only one tinkering with a HEX editor back in the days then!

Don,
I wish it was just the volume. That could be easily corrected by turning the volume up!

Markus--thanks! That is good to know. Not that it would help if the timecode itself has changed (maybe due to different edits for domestic/foreign versions of the same film0.

Another little tidbit in dealing with DTS timecode that may be relevant...

Back when they changed the format of the .aud files to .aue on the newer disks, they changed the way that the timecode was printed to the film. The serial number of the feature used to appear at regular intervals in the timecode but it was changed to an arrangement that was encoded in such as way as to prevent the player from reproducing the content if the serial number arrangement in the timecode wasn't correct. It was some sort of binary encoding because the frequency of the serial number occurrences was in factors of 2. Sometimes is was every 4, 8, or 16 frames and I didn't have the time or patience to try and figure it out. I had a DTS timecode generator that I would use for testing DTS units on the bench and needed to use old discs because the new timecode security scheme was never released for the timecode generator. I was dealing directly with the timecode generator manufacturer and once we started delving too deeply into it, we received a DMCA notice and all work on the project stopped. After that I just defaulted to the Titanic sound track because it was released before the security scheme and used three discs so I could exercise three drive units and monitor for drop outs. I have that soundtrack darned near committed to memory.

If the reels are the same edit and someone has just changed the serial number for another country then changing the serial number in the file will make the DTS sound match the reel.

Hey Greg if you are looking for a timecode generator I have a program I wrote in python that will make a Raspberry Pi output a DTS track that can be plugged into the DTS reader input on any DTS player. I've only tested it with older movies but it is completely customizable. Can program a serial cue whenever you want.

I'm curious about the serial number security feature; did it just prevent playback or what happened when it didn't get the right arrangement? Did it happen at the start of a reel or random places?

That's interesting Greg because I have been able to play newer releases like "Dunkirk" and "The Master" using a DTS TC generator. However as I mentioned before you have to select and arm each reel I don't remeber but I think that was also the case with older disks too?

This would make some degree of sense according to what Greg is saying, as the discs for Dunkirk (at least the ones we have here) have the .AUD format files on them. Perhaps they decided that piracy was not so much of an issue nowadays given how niche the DTS system has become.

Good point, that was one of the advantages of DTS - the ability of changing the language by swapping the disks.

It happened to me in the mid-1990s, with an entirely forgettable movie called Dante's Peak.
