AUDIOVIZOR vs projectM

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.

projectM is an open-source music visualizer that turns audio input into visuals in real time. Its libprojectM library is intended for application development and reimplements Winamp MilkDrop, including support for user-contributed visualizations. The library analyzes PCM audio with beat detection and FFT, then renders visuals using OpenGL. Preset files define looks through pixel shaders and MilkDrop-style equations, but libprojectM does not include presets. The projectMSDL desktop frontend listens to audio input and produces visuals; standalone options are listed for Windows, macOS, and Linux. The library documentation lists builds for Windows, Linux, macOS, iOS, Android, and WebGL/WASM. The core library is licensed under the GNU Lesser General Public License 2.1. projectM is free and open source. Its available end-user frontends are development previews that may be incomplete or contain bugs, while Android apps linked by the project are not created or supported by projectM developers. Third-party integrations including Kodi, Silverjuke, and VLC are supported by their respective developers, not the projectM team.
