flac dev - Sep 2007 - New tags for better transitions between tracks.

Hi All,
    I've been playing with some new metadata tags for a while and I 
think I'm ready to share the joy. I've set up a puny webserver at 
http://phippo.is-a-geek.com/mixramp.html (please don't slashdot it) with 
some patches to implement and use the tags.

The patch for metaflac applies to the current CVS FLAC and adds the 
command line option --add-mix-ramp. This is a shameless rip off of the 
Replay Gain code and it creates some new VC tags.

The other patches are for mpd and mpc since that's what I use to listen. 
The patches apply to current SVN.

I'd like to get this into FLAC so I don't have to maintain the patch, 
should I submit a feature request?

Cheers,
Tim.

I don't know the validity of this crossfading-metadata technique,
because I haven't tested it yet.  What's scary though it's the use
of
code from different projects with different licenses, when the patch
itself claims no license.  This makes it impossible at the moment to
add it to the FLAC trunk due to possible licensing conflicts.

My suggestion: make it more clear what code did you take from other
projects, what licenses were used, and what license does your patch
fall in.

Maybe I shouldn't have used the word stolen while SCOx are in the news ;-)

What I did for the metaflac patch was to copy the method used to 
generate Replay Gain tags and extend it to record the time and volume 
profile at the start and end of tracks. The Replay Gain code is from 
metaflac so I guess that's covered by GPL. I'm happy to give the 
copyright to the metaflac patch to Xiph or anyone that will put it in 
FLAC. More than happy, to paraphrase Spiderman: With great copyright 
ownership comes great hordes of blood-sucking ambulance-chasers.

The MPD patches were done in a similar way using the Replay Gain and 
crossfade code from MPD. There isn't any code copied from one project to 
another.

Hope this helps,
Tim.
