Add more audio visualization styles

Add more audio visualization styles like Astrofox and Wav2Bar.
(both projects are on GitHub. Why the hell, link is disabled?)

Showcase video added below for reference.
(Again, why the hell link is disabled?)

Because you’ve been here 3 times in 2 years, and didn’t read the onboarding docs (otherwise you’d know the answer to this ; ), so the software still has you filed under “not sure if you’re a spammer or know how things work around here”.

It will lift that restriction automatically once you prove that suspicion wrong.

All audio visualization styles are effects provided by ffmpeg (avfilter), frei0r, or melt. Kdenlive doesn’t have its own effects created by the team.

If you want additional effects, you can create them yourself in any of the liobraries mentioned above or contact the respective team and ask for one (good luck with that, I might add).
