Open-Source DVD-Audio project (1st alphas released)

Kurtnoise · 4th March 2005, 10:31

I quote the author Dave Chapman who described this project on HA. It's a good idea I think...

Quote:

I want to announce the fact that I've started a project to develop a set of open source DVD-Audio tools.

I'm not interested in playing commercial DVD-Audio disks so I am ignoring MLP and the various copy prevention and watermarking schemes.

But what I am aiming to do is to try and publically document the format of the various files inside the AUDIO_TS directory and develop open source authoring and playback tools for uncompressed, unencrypted DVD-Audio disks.

The project home page is at http://dvd-audio.sourceforge.net and there is a mailing list there which anyone is welcome to join.

That site currently contains an in-progress "unofficial DVD-Audio specification" - which I would welcome contributions to.

Regards,

Dave.

WOW,

I hope this project takes off; this is the first time I have heard of anyone venturing in to these uncharted waters before open source wise.

I would much rather convert some of my CD's to multi channel DVD-A than to DD or DTS even if there was a freeware encoder for it. I am no programmer so I really can’t help you but I will be keeping close tabs on this project that’s for sure.

Good luck with this!

The 1st alpha is out...

Quote:

This initial "alpha" release of dvda-author is capable of taking up to 99 16-bit Stereo WAV files at any of the samplerates supported by the DVD-Audio standard (44.1KHz, 48KHz, 88.2KHz, 96KHz, 176.4KHz or 192KHz) and creating an AUDIO_TS directory compatible with hardware DVD-Audio players.

The next developments will be support for multiiple DVD-Audio "groups", 20-bit and 24-bit files and 6 channel surround. A cross-platform GUI version of dvda-author is also in development.

dvda-author is available to download from http://dvd-audio.sourceforge.net/alpha/ and usage is documented at http://dvd-audio.sourceforge.net/howto.shtml

The dvda-author release contains both a Windows executable and full source code (suitable for Linux, Mac OS X and any other platform with a C compiler) and is distributed under the terms of the GNU General Public License (GPL).

SiXXGuNNZ · 17th March 2005, 00:35

Sure, I'll try to make a torrent, never have before.

It's just the MLP files from the Creative demonstrations disk, I also have an unprotected DVD-Audio

Well so far, no go at the torrent, it's 202MB, any ideas?

Wrong, or I don't understand what you said (your english is crappy

)...you can grab the sources via the CVS and compile those files under Linux w/o problems.

@Sycho : have you got a decoder to play these files ? If yes, what kind of decoder...

BTW, there is a new alpha version.

Quote:

The main change is support for multiple groups. e.g. the command

dvda-author -o DVD -g file1.wav file2.wav -g file3.wav file4.wav

will create two DVD-Audio "groups", each containing 2 tracks.

Does anyone have already tested this tool ?

Goto driver heaven and ask for the feature presention disk for the audigy 2 zs and then extract the mlp files and the creative player, which is built into the flash program, although there are .exe files hanging around with the mlp's

I have tried this DVD-A tool....very nice!!!!

Works perfectly on my 2 DVD-A players...Toshiba 4800 and Denon 2910

j_olson · 22nd March 2005, 00:47

Very nice idea

planet1 · 23rd March 2005, 00:31

Amazing, and I thought open-source DVD-Audio tools would never appear cause everyone going to use that SuperAudio C"rap"D.

Cant wait for the stills to be implemented (nice lyrics, covers ...)

For those who are going to make some fine compilations out of their CD collections and want to add DVD-Video compatibility:

-BeSweet/SSRC can resample PCM to 48kHz

-ffmpeg can encode to AC-3 @ several bitrates

From the Mailing-List :

Quote:

This is just a bugfix release - it fixes the problem with a group
containing more than about 50 tracks overflowing the ATSI. The ATSI
(ATS_0X_0.IFO) is now either 2 or 3 sectors, depending on the number of
tracks.

Kurtnoise · 26th March 2005, 09:08

There's a new alpha release - adding 24-bit Stereo support.
