BeatDrop Music Visualizer vs Radiance

BeatDrop Music Visualizer is a Windows desktop visualizer built around a custom MilkDrop2 engine. It responds to speaker or microphone audio, including sound from media players, and includes more than 10,000 presets alongside compatibility with MilkDrop.milk presets. Visual tools include custom waves and shapes, beat detection controls, transitions, shader caching, and drag-and-drop preset loading. Presets can react to mouse and keyboard input, while shaders can use FFT and waveform data as well as system time and date. It also supports synchronized LRC lyrics, a timestamp editor, and a local lyrics cache; matching lyrics are fetched from LRCLIB. Spout can route visuals to supported apps including OBS, Resolume, TouchDesigner, and Unity. On Windows 10 version 1809 or later, system media controls provide now-playing details, playback position, and seeking. The normal build supports Windows 8.1, 10, and 11; an OldOS build covers Vista through Windows 11. The free, open-source software costs nothing. Requirements include 2 GB RAM, a WASAPI-compatible sound card, and a compatible GPU.

Radiance is free, open-source video art software for live performance, including VJ work. It runs on Linux, macOS, and Windows. Performers can work with more than 150 GPU-accelerated WGSL effects and edit them live. MPV integration opens video clips, images, files, webcams, live streams, and YouTube videos. Beat detection uses incoming audio as a shared time reference for effects. Radiance can send output to one or more screens and includes a projection mapping editor. The software is released under the MIT/X11 License. YouTube videos loaded by URL require yt-dlp to be installed separately. Building from source requires Rust, Cargo, and dynamically linked libmpv. The project README notes that MIDI controller input and TCP output for LED displays are absent from the rewrite compared with version 0.6.1. Radiance is listed at free.
