I mean I'd like them actually on the timeline. Sorry for being unclear. I would like to be able to select an arbitrary spot in the Spectrometer window, and somehow place a label on the time that correlates to the selected spot in the spectrometer. > I suggest that you introduce keyframes in the plugin if it doesn't have > them, > yet.

Hmm, labels from keyframe data also seem useful if I am unable to edit the EDL labels directly. >> Question3: When I'm done, who/where should I submit the patch? > > Post it here. I've got an early version that is working a lot better than the old spectrometer already, so I thought I should submit the attached patch. My next milestone is to add BC_FPot to control the "WINDOW_SIZE" and "STEP", so that you don't have to recompile the plugin to change these key parameters. Here's a screenshot of how this updated Spectrometer looks like: http://img244.imageshack.us/my.php?image=spectromi3.png For some reason, a ton of unnecessary information was generated when I ran the "svn diff" command in the main directory... so I just ran svn diff in the plugins/spectrogram directory. --Percival ------=_Part_5318_7254999.1215050772921 Content-Type: text/x-patch;
