Visualization of live audio using gifs. This is based on Scott W Harden's "Realtime FFT Audio Visualization with Python".
You can use dough, watermelon or add a new gif like this:
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!
apt-get install python-pygame python-scipy python-numpy python-pyaudio
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".
I uploaded some demos to YouTube.
