Problem trying to play DTS audio

[seven_deuce offsuit]

I made a DTS WAV out of DTS Surcode but whenever I try to play it I only hear static. So then I decide to burn my video with the audio on a DVD so I can try it on my DTS compatible speakers but with no avail, static again. I have the speakers connected to my PS3 and have been able to play blu-ray movies with DTS audio without any problems. Is it an encoding problem? I used the V.I. plug-in in Sound Forge to create my 6 WAV files encoded at 24 bit (I also tried 16 bit) fed to DTS Surcode. Is there some sort of way I can check if the DTS WAV is all right by decoding it and then playing it or something? I want to make sure everything is ok with it on my computer first before I decide to risk damaging my speakers again.

I'm guessing that your conversion didn't work.

You can test .dts files in VLC (which has it's own internal codecs, so no need to install anything else)

Run it through DTSParser

The DVD-Video specs require "pure" DTS.
Surcode can output both "pure" DTS streams and .WAV-wrapped~DTS.
The user is allowed to choose which format is best for their needs.

So I just run it through DTS Parser and that's all?

I can't find an option that says that.

Ok, now I've got it to play on my computer using the AC3filter, but I'm just curious as to why Mediainfo and Gspot say it's only a 2 channel wav.

DTS audio data can be stored in three different data file: Compact (*.cpt), Padded (*.dts), and Wave
(.wav). Each of these has its uses. DVD authoring systems vary in their handling of these file formats, but
in general:

• Compact (*.cpt) file format is the one most used for DVD authoring.
• Some systems also accept files in the Padded (*.dts) format.
• .wav format files are useful for quality assurance because .wav is a standardized digital audio
file format playable on a variety of digital audio systems. .wav format files are not used
directly for authoring.

Authoring systems vary in the way they handle these file types, and encoding systems also vary in the
way they are specified. The specifics of individual systems are described later in this document.

Compact (*.cpt) File Format

Encoding systems for DTS provide a default or option to save files in the Compact format with the file
extension “.cpt”. Compact format files are encoded with only audio, timecode, and header information,
and are coded in “Motorola” (high-order byte first) byte order.
Not all DVD authoring systems recognize the “.cpt” extension. Depending on the system, you may have
to set the list of file types displayed in the Open File dialog to “All Files” in order to see the *.cpt files. In
certain cases, you may have rename files to “.dts” in the file system in order to use Compact format files
in authoring.

Padded (*.dts) File Format

Most of systems for encoding to DTS define the option of Padded (*.dts) file type by selecting this
extension when the file is saved. Some systems define this as an option in encoding labeled as “Pad Files
with Zeroes”, or similar wording. “Padded” files include extra zeroes in addition to the audio payload and
timecode/header information. These files are stored in Motorola byte order.
Most DVD authoring systems are able to use both Padded and Compact file types.

.wav File Format

All DTS encoding systems provide option to save in “.wav” format, consisting of padded audio data
stored in “Intel” (low-order byte first) byte order. These are identical in format to ordinary audio .wav
files, can be handled by standard digital audio application, and can be played in various ways.
This file type is not used directly in DVD authoring, but is often useful for auditioning. Some encoding
systems provide an option to generate separate *.wav files automatically for this purpose.

Unfortunately I'm using DVD Architect and it has no DTS support. If I import a WAV DTS it's still going to be static. What software can I use to mux AC3 and/or DTS streams? I've tried Muxman but always get an error when trying to mux DTS. I've read somewhere that ImagoMPEG-Muxer can mux DTS streams but I have yet to find that option.

dvd-lab pro might work. it accepts normal dts, but i've never tried dts wav.

media player classic will play dts wav files. other dvd software should also.

Time to try DVD-lab Pro, I guess.

As it should be . Your DVD player must output the WAV-wrapped "noise"
onto an external digital-audio amplifier.

I've tried Muxman but always get an error when trying to mux DTS.

What is the error message? Happens with any type of DTS audio?

[seven_deuce offsuit]

I've tried it with compact and padded DTS and the error shows: "Multiplex operation failed. Probably caused by excessive bitrate".

Is it referring to the system bitrate? I don't understand why I would get that message even when the total data rate is only about 8mbs.

Problem with DVD-lab Pro is it's not free.

Now you know what my current sigfile is all about.

GUI for DVDauthor says it supports DTS (but I have never used it).

[seven_deuce offsuit]

If it can support DTS then I'll just use it to mux my audio and author with DVD Architect. Thanks, I'll try it out.

Yeah, lol.

I just found out after looking at Mediainfo that supposedly the DTS audio stream I encoded from Surcode is actually DTS-HD. Does anyone know if it is? I've always thought it was just standard DTS.

[Midzuki]

AFAIK DTS-HD is not valid for DVD-Video.

Have you taken the time to RTFM
