Oscillody

About Oscillody

Oscillody is an easy-to-use program developed by me to create audio visualizers, whether it is for music, or recordings.

It displays the waveform of your imported audio. You can customize the visualizer to your taste with plenty of options, export the result as a video, and do whatever you want with it.

This project started on July 6, 2024, as a personal challenge to make audio visualization using the Godot Engine, a free and open-source game engine. Since this is my first project, it served as a learning experience for future game projects.

It was built using Godot's ability to return audio sample data, perform FFT, and export videos.

I've always liked audio visualizers, especially the ones with waveform display. However, it was not easy for me to find a simple program to create such visualizers for my videos, without using high-end video editing software.

Even if there might be options around nowadays, this project also serves as a free and simple alternative for those who just want to create a simple visualizer for any reason, without having to tweak a lot of settings or spending money on a video editor.

This is a free and open-source software, however I'm not accepting code contributions (pull requests) at the moment!

Planned Updates

- Performance mode (captures and displays audio from an input device) (Engine-side, input device capture is currently slow)

- Faster rendering (Engine-side)

- Proper rendering and encoding progress bar (might be Engine-side)

- Audio spectrum (along with smoother audio reaction) (Engine-side)

- New background and post-processing shaders

- Improve existing shaders

- Option for multi-colored waveform

- Option for video background

- Allow reactions to happen at element's 0 strength

- Make shader speed framerate-independent

- Font preview

- Option for fade in/out

- More export quality options

- New icon controls

- New shadow controls for title and icon

- Option for background shader rotation

- New reaction controls

- Undo and redo

- Waveform optimization

- More advanced title controls

- Linux support

- Allow importing with drag & drop

- New themes and theme swapper

Known issues

- Waveform display may look incomplete depending on your output device and audio settings (e.g. some wireless headsets).

- Spectrum data (used for audio reaction) returns jittered values.

- Audio in exported videos are always 44.1kHz.

- MP4 videos may have some small audio artifacts (you have the option to encode yourself).

- Stutters (in preview only - doesn't happen on all computers)
