DTS to wave

[Spc01]

Hi,
Is there any good DirectShow filter that opens DTS 5 Channel audio track at 192kHz sampling rate?

I want to convert 6 channel dts (192kHz) track to 6 channel wave (192kHz) file.

Any ideas ?
DTSWAVSource.ax doesn't do anything it just sits there and idles i think this is because it doesn't support 192kHz sampling rate.

Try foobar2000 (http://www.foobar2000.org/)with foo_dts (http://pelit.koillismaa.fi/plugins/show.php?id=177) plugin.

Try ffdshow. In the config, enable DTS decoding and tick Search for DTS in WAV. Then put Uncompressed audio to All Supported.

DTS does not do 192 yet, unless you have got your hands on a track from the new DTS-HD spec.
DTS usually only goes up to 96/24 max.
For the some info on the new HD specs have a look at this:
http://www.dtsonline.com/pro-audio/mas_encoding.php

And just down the page under DTS-HD it states 192khz in 2 channel only.

Yes actually i've noticed that.
DTS standard is 48kHz, 16bit 6 channels (5.1).

WinDVD 6 Reports:
Stream:
Type: DTS
Bitrate: 768 Kbps
Number of main channels: 5
LFE Channel: Present
Sampling Frequency: 192kHz
Bits Per Sample: 16

PowerDVD 7 reports:
Stream:
Type: DTS
Bitrate: 768 Kbps
Number of main channels: 6
LFE Channel: Present
Sampling Frequency: 48kHz
Bits Per Sample: 16

So i think PowerDVD is correct but when i try to convert it to 6 channel wave file it does not work with the directshow filter i mentioned.
I'll try ffdshow and foobar tomorrow.
This is the first DTS that i can not decode correctly using these: dtsac3source.ax, DTSSource.ax, DTSWAVESouce.ax.
I've done alot of dts conversion and never had any problems with it.

tnx for replys.

Try foobar2000 (http://www.foobar2000.org/)with foo_dts (http://pelit.koillismaa.fi/plugins/show.php?id=177) plugin.
Thanks dude!
I will try this one ;)

[Spc01]

Awesome.
Foobar works.

:D

Hmm now how to convert it to 6 channel wave file...
Ok found it.

Many thanks.


I did some research and found out why it didn't work with directshow filters.
The thing is that this dts file doesn't have a WAVE header so directshow filters did not recognize it as a dts file..

Usually it's the other way around. DirectShow filters won't recognise it if it DOES have a WAV header. ffdshow is the only one I know that will, it also recognises it without a WAV header. Make sure it's named .dts if it has no header though.

[Spc01]

That's WAVE header ?

:confused:

This is a wav header from a wavdts (44.1KHz):
Offset | 0 1 2 3 4 5 6 7 8 9 A B C D E F |
---------|--------------------------------------------------|-----------------
00000000 | 52 49 46 46 24 00 55 01 57 41 56 45 66 6D 74 20 | RIFF$.U.WAVEfmt
00000010 | 10 00 00 00 01 00 02 00 44 AC 00 00 10 B1 02 00 | ........D¬...±..
00000020 | 04 00 10 00 64 61 74 61 00 00 55 01 FF 1F 00 E8 | ....data..U.ÿ..è
This header is identical to a stereo PCM 16 bit int 44.1KHz wav file.
Only if is open like a wavdts we can extract the dts stream, if is open like a regular wav the output is hiss.

[Spc01]

Yes i know that.
As you mentioned it has to have RIFF wave header in the header.. to have a wave header....
If you look at my sample it does not have it.

:)

Some dts frame header:
Offset | 0 1 2 3 4 5 6 7 8 9 A B C D E F |
---------|--------------------------------------------------|
00000000 | 7F FE 80 01 FC 3C 3E D2 75 E0 0D 3A 00 09 8C 63 |
------------- 48 kHz, 768 Kb/s, 5.1, 16 bit source PCM ------

00000000 | 7F FE 80 01 FC 7C DF F2 62 C0 0D 3B 80 09 EF 7B |
----------- 44.1 kHz, 1411.2 Kb/s, 5.1, 24 bit source PCM ---
A dts frame header always begin with a 32 bit sync word: 0x7FFE8001, really I don't know what is your header.

[Spc01]

Maybe complette header has been removed ?
:confused:

[Borbus]

Did you actually demux this from a DVD Video or is it still in a VOB?

[Spc01]

It is demuxed.
This is a demuxed dts stream from DVD (vob).

Excuse me, but what hex editor do you use to get those headers tebasuna51, please.

[tebasuna51]

Excuse me, but what hex editor do you use to get those headers tebasuna51, please.

I use WinHex, but to see the headers, any hex editor can work.
Also VirtualDub have a hex editor in Tools.
