Audio Visualizer Python
We need a good name that is not as generic as "audio-visualizer-python"!
This is a little GUI tool which creates an audio visualization video from an input audio file. Different components can be added and layered to change the resulting video and add images, videos, gradients, text, etc. Encoding options can be changed with a variety of different output containers.
The program works on Linux, macOS, and Windows. If you encounter problems running it or have other bug reports or features that you wish to see implemented, please fork the project and submit a pull request and/or file an issue on this project.

Installation
Installation on Ubuntu 24.04
- Install dependencies:
sudo apt install ffmpeg pipx python3-pyqt5 - Download this repo and run
pipx install .in this directory - Run the program with
avpfrom terminal
Installation on Windows
- Install Python from the Windows Store
- Add Python to your system PATH (it should ask during the installation process)
- Download this repo (extract from zip if needed)
- Download and install FFmpeg. Use the GPL-licensed static builds.
- Add FFmpeg to the system PATH as well (program will then work anywhere)
- Alternatively, copy ffmpeg.exe into the folder that you want to run the program within
- Open command prompt,
cdinto the repo directory, and run:pip install . - Now run
avporpython -m avpfrom a command prompt window to start the app
Installation on macOS
- We need help writing instructions for macOS, but the program should work in theory.

Commandline Mode
Projects can be created with the GUI then loaded from the commandline for easy automation of video production. Some components have commandline options for extra customization, and you can save "presets" with settings to load if the commandline option doesn't exist.
Example/test command
- Create a video with a grey "classic visualizer", background image, and text:
avp -c 0 image path=src/tests/data/test.jpg -c 1 classic color=180,180,180 -c 2 text "title=Episode 371" -i src/tests/data/test.ogg -o output.mp4
- See more about commandline mode in the wiki!
Developer Information
Known Working Versions of Dependencies
- Python 3.10
- FFmpeg 4.4.1
- PyQt5 (Qt v5.15.3)
- Pillow 9.1.0
- NumPy 1.22.3
Getting Faster Export Times
- Pillow-SIMD may be used as a drop-in replacement for Pillow if you desire faster video export times, but it must be compiled from source. For help installing dependencies to compile Pillow-SIMD, see the Pillow installation guide. Then add the
-SIMDsuffix intosetup.pyand install as usual.
Developing a New Component
- Information for developing a component is in our wiki: How a Component Works
- File an issue on GitHub if you need help fitting your visualizer into our component system; we would be happy to collaborate
