Extracting DTS/DD Stream from encoded WAVs

[Raptus]

Hi,

I'd like to know if there is a way of extracting the DTS or DD streams from those WAVs that are meant to be burned on CDR. So far I only found info on how to create them ;)
I guess it involves only some fiddling with the header, but which program I use for that?

Basically what you need to do is remove the first 44 bytes of the WAV file, and then change the endianness of the rest of the file.

I dunno any app that does it. Shouldn't be hard to make one, though.

too bad I can't code. :(

I just don't want to burn a CD to listen to that demo surround material you get on the net. If I could get SPDIF passthrough to work for those files... but so far it only works for native DTS and AC3 files (the ones demuxed from DVD)...

Hmm. i think you should try this (http://dc0der.is-a-geek.org/wav2dts.exe) :)

It's pretty simple, but should work. Oh, the syntax is:


wav2dts infile.wav outfile.dts

Have fun.

Umm... AC3 FAQ # 15 or DTS FAQ #6 anyone? Besplit can be used to extract DTS or AC3 from DD- or DTS-wavs.

An example is: BeSplit -core( -input live.wav -output e:\track01.ac3 -type ddwav -fix )

I tried BeSplit before, but I get following problem:
After confirming the CLI command the program returns the default info text (like when You just type "besplit" with no params)... BeSliced generates 0 byte files for AC3-WAVs and 512byte files for DTS-WAVs :confused: (BTW: BeSplit has no option for DTS, I guess using the AC3 option will do just fine).

The files I have are the ones You can get here:

Ok I found an error in your FAQ:
There is no -output param, You have to use -prefix instead.

Using -prefix I got BeSplit to extract an AC3 from my AC3-WAV file, but which doesn't playback on MPC+AC3filter as do AC3 files demuxed from DVD... :rolleyes:

I'd recommend trying the latest beta, and post your logfiles for additional help.

Ok, now I had the time to test a bit further:

Wav2dts did not return valid files (could'nt be played back/SPIDIFed/Muxed).

BeSliced 0.9b still produced 0byte files on my DD-WAVs. The extract DTS could be played back, although they were silent and weren't recognized as DTS when SPDIFing them... :confused:

I'm suspecting something's wrong with my files, although thats hard to believe given the rather oficial source (link in previous post). Would someone mind to check?
