Hi, Hopefully this is within the scope of this list but following a lot of recent googling, there doesn't appear to be any interest in "open-sourcing" anything related to DVD-Audio.
As you may know, commercially authored DVD-Audio disks have three very unfriendly features - encryption, watermarking and Meridian Lossless Packing (MLP). I am assuming that these are some of the reasons developers have not become interested in DVD-Audio. However, none of those features are compulsory, and if you remove those obstacles (which I am not interested in overcoming - simply avoiding), you are left with a standard which allows 18 combinations of samplerate and sample wordsize for 2-channel stereo audio (including 16-bit/44.1KHz RedBook, and going all the way up to 24-bit/192KHz), plus a range of 6-channel uncompressed surround sound formats. My aim is to produce a set of GPL'd tools to both author, "un-author", and play such unencrypted, uncompressed disks, and am curious to know if any other developers have an interest in this area or not. To this end, I've started the "dvd-audio" project at sourceforge - http://sourceforge.net/projects/dvd-audio/ I have not yet populated the site with HTML content or any of the software I'm in the process of developing, but there is a "dvd-audio-devel" mailing list which anyone is welcome to subscribe to. I should reiterate that I'm not interested in investigating features such as encryption or MLP - I simply wish to be able to author my own unencrypted and uncompressed DVD-Audio disks using my own music, which I can then play back either on my hardware DVD-Audio player or on my PC, all using free software Regards, Dave.
