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. The component setup can be saved as a Project and exporting can be automated using commandline options.

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 send me a pull request and/or file an issue on this project.

I also need a good name that is not as generic as "audio-visualizer-python"!

Dependencies

Python 3, PyQt5, pillow-simd, numpy, and ffmpeg 3.3

Note: Pillow may be used as a drop-in replacement for Pillow-SIMD if problems are encountered installing. However this will result in much slower video export times.

Installation

Manual installation on Ubuntu 16.04

• Install pip: sudo apt-get install python3-pip
• Install prerequisites to compile Pillow:sudo apt-get install python3-dev python3-setuptools libtiff5-dev libjpeg8-dev zlib1g-dev libfreetype6-dev liblcms2-dev libwebp-dev tcl8.6-dev tk8.6-dev python-tk
• Prerequisites on Fedora:sudo dnf install python3-devel redhat-rpm-config libtiff-devel libjpeg-devel libzip-devel freetype-devel lcms2-devel libwebp-devel tcl-devel tk-devel
• Install dependencies from PyPI: sudo pip3 install pyqt5 numpy pillow-simd
• Install ffmpeg from the website or from a PPA (e.g. https://launchpad.net/~jonathonf/+archive/ubuntu/ffmpeg-3). NOTE: ffmpeg in the standard repos is too old (v2.8). Old versions and avconv may be used but full functionality is only guaranteed with ffmpeg 3.3 or higher.

Download audio-visualizer-python from this repository and run it with python3 main.py.

Manual installation on Windows

• Warning: Compiling Pillow is difficult on Windows and required for the best experience.
• Download and install Python 3.6 from https://www.python.org/downloads/windows/
• Add Python to your system PATH (it will ask during the installation process).
• Brave treacherous valley of getting prerequisites to compile Pillow on Windows. This is necessary because binary builds for Pillow-SIMD are not available.
• Alternative: install Pillow instead of Pillow-SIMD, for which binaries are available. However this will result in much slower video export times.
• Open command prompt and run: pip install pyqt5 numpy pillow-simd
• Download and install ffmpeg from https://www.ffmpeg.org/download.html. You can use the static builds.
• Add ffmpeg to your system PATH, too. How to edit the PATH on Windows.
