OK,

Believe it or not, but this is indirectly made by using sonic visualiser:
http://www.youtube.com/watch?v=tZtXsuIcqMsI was looking for a tool, which allows me to add/manage time-related metadata.
More specific, I wanted to be able to have datafiles which contain triggerpoints for use in animation.
For beatsyncing audio with video, this would be great.
SOLUTION: Sonic Visualiser and the .svl xmlformat
Also, I'm working on .svl 'datamassager' utility, which allows transcoding of svl-annotation-files to any scripting language:

Normally applications like blender,3dmax,afterfx have builtin timeline editors.
But if you are more into scripting animations, Sonic Visualiser is a great way to create datafiles for time-related events.
