That's another one but I'm glad you found that link. The one I'm referring to is called "Audio Spectrum Filter".

At least in mine, version 17.04.1 it looks like beeing totally broken. Some parameters can't be adjusted at all, and those values which are there (0) are not usable. Looks like worth reporting bug.

Searching it with google, not much to be found. For melt (angine doing rendering for kdenlive) https://www.mltframework.org/plugins/Fi ... ospectrum/

Thanks again for the link. I couldn't find anything like it. In my kdenlive its also seemingly broken. My last video used the VLC Visual effect. I also did some cool command line stuff with ffmpeg, but it seems everyone uses "After Effects" for that stuff while a few use Blender. Your thoughts?

I haven't *yet* used any audio visualization, so can't comment.

I'm not against that at all, 42low. I also prefer to stick to what I hear for the most part. I'm asking this for kdenlive because I want to create videos with certain visual effects.

This is awesome! Thanks for the links. I didn't even think to check Wikipedia for this. I'm going to try VSXu and maybe projectM tomorrow. Have you used them?

Haven't used any, so please tell us about your experiences, and wiuth VSXu, code examples would be nice bonus :-)

Had to redownload the appImage a few times before it worked. I thought I'd have to figure out FUSE first.My distro told me to check out instructions at https://github.com/AppImage/AppImageKit/wiki/FUSE. I'll report back once I've played with it a while.

Now I've looked projectM slightly. Haven't done any presets or even modified existing ones yet, but maybe I will modify some, for example to be slower, so that preset would match better to some slow, self-made track. Target is to create video for own music if I don't have suitable video material for supporting track.

Here is document about milkdrop/projectM presets: http://wiki.winamp.com/wiki/MilkDrop_Preset_Authoring

Jeax or anyone else, anything about VSXu?

Sorry for not replying to this. From what I remember, VSXu wasn't hard to too figure out but there wasn't much customization available. Since last updating this thread, I've used kdenlive and FFMPEG a lot. Haven't tried ProjectM yet.

I think VSXU has some way to program own patches, so it should have pretty much to customize :-)

Since last time in this thread, I have used and coded stuff for lebiniou https://biniou.net/

Some related links on https://wiki.thingsandstuff.org/VJing#Visualisation

IMO, nothing free has beaten ProjectM/MilkDrop for almost two decades now, stunning presets and their reactions to music with stunning transitions. Preset gathering and curation is required though. ProjectM got modern shader support in last couple of years + proper ARM support. I've got the Android app on my new phone that can run off the mic, /and/ there is an LV2 plugin version.

I've been using the ffmpeg showcqt via an mpv script visualizer.lua for the last year and a bit, very handy and beautiful for audio files.

I realised very recently that the script same developer also made a showcqt render bash script, a JS version, and Chrome extension version (they tried an FF addon but had some kind of blocker).

Here's a demo of [a hacked version of] the bash script.
