2026-01-25: this repo was made during my initial journey into audio visualization and 2D graphics. it now exists for archival purposes, and is superseded by libavz.

audioviz-sdl

my own audio visualizer, because after effects sucks.
for right now, audioviz only supports linux, but with the libraries i'm using, it shouldn't be hard to port to windows.
here's a demo: https://youtu.be/0f_oSrnT6j0

the default parameters construct a spectrum inspired by Spectrolizer

building

1. install required dependencies
2. run make
3. optionally install with sudo make install, or make install if you are root
