Open Source DVD-Audio authoring program released

I am happy to announce that I have just released the first version of dvda-author, my open source DVD-Audio authoring software. The project home page is at

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" (the DVD-Audio standard allows up to 9 groups per DVD, each consisting of up to 99 tracks), 20-bit and 24-bit audio and 6 channel surround. A cross-platform GUI version of dvda-author is also in development.

Native FLAC support will also be added in the very near future, so you can create DVD-Audio discs directly from a set of FLAC files - so there will be no need to convert to WAV first. But due to licensing issues, I will never add SHN support.

dvda-author is available to download from and usage is documented at

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).

Note that this software produces real "DVD-Audio" DVDs - you will need a DVD-Audio capable DVD player (i.e. one displaying the DVD-Audio logo) to play the resulting DVDs. They can't be played on a standard DVD-Video only player.

And before anyone asks, yes, the DVDs created by my software are both "lossless" and "gapless".

However, it is not currently possible to extract the audio back to WAV files, but that is high on my to-do list. When I do implement that, I will include MD5 support so that you can be sure that the extracted audio is bit-for-bit identical to the original.
