Projectm
ProjectM ist eine plattformübergreifende Musikvisualisierungsbibliothek und Pixel-Shader-Rendering-Engine. Sie fungiert als Tool zur Audiosignalanalyse, das Beat- und Frequenzdaten aus Audioströmen extrahiert, um Echtzeit-Grafikänderungen zu steuern.
Die Engine ist auf Kompatibilität mit dem Milkdrop-Visualisierungsstandard ausgelegt, was das Parsen und Laden externer Preset-Dateien zur Definition visueller Stile ermöglicht. Sie unterstützt die Organisation dieser Presets durch eine playlistgesteuerte Verwaltung, um Übergänge zwischen verschiedenen visuellen Effekten zu automatisieren.
Das System kann als statische oder Shared Library in externe Host-Anwendungen integriert werden. Zudem enthält es eine WebAssembly-Brücke, um hochperformante Audio-Visualisierungen in Webbrowsern auszuführen.
