AUDIOVIZOR vs Radiance

AUDIOVIZOR is a GPU-accelerated audio visualizer for making real-time 3D visuals that respond to music, with beat detection and video export. It offers more than 15 visual styles and spectrum visuals, and runs on the web and Windows. The free plan supports uploaded audio files, 15-minute sessions, community presets, and 720p video exports with a watermark. Unlimited adds microphone and system audio input, unlimited sessions, a full preset editor, cloud sync, batch export, overlays, and clean exports up to 4K. That plan also includes the Windows desktop app, which captures system audio and supports hardware-accelerated export. Unlimited costs C$4.99 a month. The maker recommends Chrome or Chromium-based browsers and notes that some features may not work in Firefox or Safari. It says it does not sell personal information or use analytics, tracking, or advertising services, and that payments run through Stripe without storing card information. The privacy policy states PIPEDA compliance and additional GDPR rights for EU and EEA users. Users must be at least 16 years old.

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.
