How to ripp DTS-stream to put on CD

[Kladden]

Hi,

Is it possible to ripp a DTS-stream and put it on a CD???
You can buy DTS-CD, so why not!
It would be great to rip Iron Maiden - Rock in rio!!!
What programs should i use to rip and author????

You can't get to the DTS stream on a video. Original DTS cds can be copied, same for a DVD with DTS content but there is no program that can seperate the streams. DTS is the only audio format that is totally hack proof, even SACD and DVD-Audio have been cracked. The only thing you could do is run each channel back into your sound card and re-record it, but you would lose a lot of quality that way.

I think there are ways to rip a DTS stream, but you would need an encoder to make another DTS stream with the right sampling frequency and correct bitrate with or without padding. I know you can use BeSure to make DTS-CDs (or for that matter DD-CDs), but I think you need to use wave inputs and you need to buy Sur-Code DTS (Sur-Code might be able to decompress DTS to wave).

What is your source? Maybe I can help you if I know what you are using as your source.

dts streams on dvds are not the same as the ones on cd. the bitrate is different, and so is the sample rate.

basically to go from dvd-video dts stream to dts-cd, the steps are:
1. convert dvd-video dts audio to 6 mono pcm wav files.
2. convert each of the 6 mono wav files to 16bit 44.1khz pcm wav files.
3. encode 6 wav files to dts wav file (use the SurCode DTS program).
4. burn an audio cd and put the dts wav file on it.

step 1 is the problem. i don't know of any software that decodes the dts stream into 6 mono pcm wav files. so currently the only way i know of doing it is to record 2 channels at a time in analogue.

[hypercube]

step 1 is the problem

I know how to to this step. 8)

1. use garphedit
2. use Intervideo Audio Decoder, DTSSource filter and a File Writer.
3. run the graph

the output file contain all decoded PCM data 6 ch 16bits signed.

SWEET :P

give the man a dollar... make that $2!

I finished DirectShow input and PCM output support in Hypercube Transcoder 3.
So, with this tools, you will be able to transcode any 5.1 stream
into 6 RAW PCM files, using the right filters...
(DTS, AC3, Dolby Prologic II, ...)

I hope to publish my release this weekend.

note that DTSSource filter does not work with DTS WAV.

To convert dts-wav to 'pure' dts use besplit:
BeSplit -core( -input live.wav -output e:\track01.dts -type dtswav -fix )

You have to get the newest besplit (v0.9b4) from dspguru.notrace.dk

[hypercube]

cool !

so it it is right now possible to convert DTS WAV to RAW PCM.

1. use BeSplit to produce .DTS
2. use Hypercube Transcoder 3 to produce 6 RAW PCM files (5.1 only,sorry !)
3. follow steps by mikk

[Fritzie]

so it it is right now possible to convert DTS WAV to RAW PCM.

Yesterday I used the new Hypercube version to do this, this tool is very easy !. And no big temp-files.

Only one problem: DTS-WAV cd's are usually 44100 kHz, and your program assumes that all incoming files are 48000 kHz, so the result is an mp2 that's 10% too fast.

Is there a workaround for this ?

[hypercube]

is there any upsampler filter around ?

if not, I will try to implement 44100hz support as input in
future release.

I haven't seen an umpsampler filter, and I'd rather not do that as I don't want to affect the original music.

So I hope you can implement 44100 hz input in the Transcoder.

[hypercube]

ok.

I have a question for you: witch version of besplit did you use ?
0.82 and 0.9b4 does not implement "-type dtswav" option.

[Fritzie]

I use 0.9b4, this is my commandline:
BeSplit -core( -input source_dts.wav -output Raw.dts -type dtswav -fix )

I downloaded my version from this URL:
http://dspguru.notrace.dk/BeSplitv0.9b4.zip

[hypercube]

forget my last post, I found the right syntax with BeSplit v0.9b4

besplit -core( -input DTSWAV.wav -type dtswav -output DTSWAV.dts )

[hypercube]

I found a piece of DTS spec ! argggl ! it seems to be public since december 2002. I've got the power ! tirlidooo ! pom pom !

I know how BeSplit work. This not so complicated.
Are you ready to speak about bits ?

DTS/WAV are encoded 16 bits per 16 bits but the 2 first bits
are unused, so we can say, DTS/WAV data are encoded in 14 bits.

DTS/DVD are encoded in continuous bit stream.

How to convert ? Here the scheme:

the first bytes of a regular DTS/DVD stream is a sync word:

7F FE 80 01 => 01111111 11111110 10000000 00000001

the same data appears in DTS/WAV like this:

FF 1F 00 E8 F1 07 => 11111111 00011111 00000000 11101000 11110001 00000111
x x x
swap word => 00011111 11111111 11101000 00000000 00000111 11110001
AND MASK => 00111111 11111111 00111111 11111111 00111111 11111111
=> 00011111 11111111 00101000 00000000 00000111 11110001
<<2 => 01111111 11111110 10000000 00000001 11111100 01xxxxxx


et voila !

I'm going to program this...

Is there some ideas related to DTS should I implement in a tools ?

[Fritzie]

Cool!

I recognize your drive to bite into a problem like a pittbul

I've finally completed my .bat-script to convert a dts-wav to an mp2. The steps are:
besplit (convert to raw.dts)
Graphedit (I still have to do this manually, convert raw.dts to raw.pcm)
raw2audio (convert to aif)
chtype (convert to wav)
besplit (extract channels)
audio2raw (convert channels to pcm)
raw2audio (multiplex channels to aif, have to do the above to switch a couple of channels (l-c-r-ls-rs-lfe to l-r-c-lfe-ls-rs))
pub_enc (convert to mp2)

Using the Transcoder to do this would be a lot easier

I would be nice if it was possible to choose the output-type from aif/ac3/6 separate channels/mp2.

yep ! I made a pretty tool to convert DTS/WAV into DTS/DVD, it works fine.


[quote]I've finally completed my .bat-script to convert a dts-wav to an mp2.[code]

wow. don't show this to any newbies... they go to kill themselves !

Using the Transcoder to do this would be a lot easier

certainly. You have to make a lot of convertion like that ?

You want to transcode anything into anything. I know. Everybody want
that today.

[Fritzie]

Recently I had to convert +- 5 DTS CDs, so not a lot.

The most of what I really want is already in the converter:
DTS to MP2 (only no 44.1kHz input yet)
normalize
ability to select only a part of the file (is this already possible?)
ability to switch channels if necessary
output bitrate higher than 384, but I still have to check if my DVD-player likes it

[hypercube]

ability to select only a part of the file

for instance you can start at a specified position, but HT3
stop a the end of the stream.

output bitrate higher than 384

this is impossible because 384kbps is the higest bitrate for
Mpeg multichannel.

I am working on a source filter very similar to DTSSource.ax,
to convert DTS/WAV files. But it was hard. fortunatly, I found
the DTSSource author.

Hi Fritzie and Hypercude,

Is it possible for you to compile a small "how to make dts cd's" guide.
I'm not a newbie, but .... perhaps just lazy.

[CaptainC]

I have a DTS wav file that i have downloaded I want to encode this to Mpeg multi so that i can play it on my dvd player, my player excepts DTS discs but will not output 5.1 (no sound at all).I have read the guide here but do not know how to run besplit i have the required besplit version but do not understand how to run the .exe file i similarly have the same problem with AC3 fix.
I would aprreciate any help or guide to use this or these tools.
Im not a newbie just trying more advanced techniques.
