Visualizes live audio using gifs.

gif-music-visualizer

Visualization of live audio using gifs. This is based on Scott W Harden's "Realtime FFT Audio Visualization with Python".

Prepare gif

You can use dough, watermelon or add a new gif like this:

Use ImageMagick: convert -coalesce image.gif image.jpg

Create a directory in the frames subdirectory and copy the image frames into it.

If you found a cool gif, please send me a message/pull request. Thanks!

Dependencies

• pygame
• scipy
• numpy
• pyaudio

Debian:

apt-get install python-pygame python-scipy python-numpy python-pyaudio

Usage

Play some audio and run visualizer.py. Press F11 to toggle full-screen mode. Use Escape to exit.

Visualization moves but no audio playing?

I had to use pavucontrol (PulseAudio Volume Control apt-get install pavucontrol) to select "Analog Stereo Output" instead of "Analog Stereo Duplex" (Configuration tab). If you want to use an external input device (like a microphone) use "Analog Stereo Input".

Demo

I uploaded some demos to YouTube.
