I want to show the spectre of the track in the tracklist.
Can you explain why this is important to you and how this could benefit others?
Perhaps also where you would locate it or how it would be accessed.
This will help understand and raise interest.
it's very useful for gauging the overall sound of a track (red - bassy, green/yellow - warm, white - full and bright, blue/purple - trebly), and the rough track layout. i've often wished for a little thumbnail of the stripe in the browser! it could even be a little preview player!
You can take a look at rekordbox, they have it.
You can also see if and where you have hot cues. It's pretty neat.
A column in the browser for the waveforms as a small preview would actually be nice for the workflow.
It's a shame that it has so few votes, because it would provide a lot of information, but unfortunately it's not a game changer.
