A collection of pulseaudio visualizers

Set (using pavucontrol or pactl) the default source to the monitor of your speakers and start the visualizer with

cargo run --release --bin pa-visualizer-<visualizer-name>

pa-visualizer also supports rendering a visualization. To do so, first convert your audio file to a .wav (Format: 32 bit float, Samplerate: 8000). Then add the following to the config of the visualizer you want to render:

RENDER_MODE = true
RENDER_FPS = 30.0
RENDER_SOUNDFILE = "name-of-your-file.wav"
RENDER_OUTPUT_DIRECTORY = "name-of-the-folder-to-put-the-frames-in"

Start the render by simply starting the visualizer:

cargo run --release --bin pa-visualizer-<visualizer-name>

Finally, convert the images to a video, for example using the following ffmpeg command:

ffmpeg -framerate 30 -i frames/%06d.png -i name-of-your-file.mp3 -c:v libx264 -preset slow -crf 22 -pix_fmt yuv420p -b:a 128k output.mp4

A simple debug visualizer, printing the left and right spectra to the terminal window

A wrapper to write visualizers in python. Does not support rendering atm!

A basic visualizer made with sfml

A visualizer made using sfml with a wireframe style

Same as wireline, just "wrapping" it around a circle

A 3d visualizer, written using glium based on the Demo "No Ambition" by Quite & T-Rex

Taking the noambition visualizer to the 'next' level ... Thanks to offdroid, for help with implementing this ...
