Projectm
ProjectM es una biblioteca de visualización de música multiplataforma y motor de renderizado de sombreadores de píxeles (pixel shader). Funciona como una herramienta de análisis de señal de audio que extrae datos de ritmo y frecuencia de flujos de audio para impulsar cambios gráficos en tiempo real.
El motor está construido para ser compatible con el estándar de visualización Milkdrop, lo que le permite analizar y cargar archivos preestablecidos externos para definir estilos visuales. Admite la organización de estos preajustes a través de una gestión basada en listas de reproducción para automatizar las transiciones entre diferentes efectos visuales.
El sistema se puede integrar en aplicaciones host externas como una biblioteca estática o compartida. También incluye un puente WebAssembly para ejecutar visualizaciones de audio de alto rendimiento dentro de los navegadores web.
Features
- Fragment Shader Rendering - Uses pixel shaders to perform per-pixel visual calculations on the GPU for dynamic audio-driven graphics.
- Audio Spectral Features - Extracts spectral frequency-domain characteristics from audio signals to drive dynamic visual changes.
- Audio FFT Analyzers - Uses Fast Fourier Transform to extract beat and frequency data from audio streams.
- Audio Frequency Analysis - Implements real-time decomposition of audio signals into frequency components to drive visual effects.
- Real-time Visualization - Provides immediate graphical rendering of audio signals reacting to frequencies and beats.
- Audio-Reactive Visuals - Generates generative imagery that changes properties in real-time based on audio signal analysis.
- Audio Visualization Libraries - Provides a cross-platform library for rendering audio-driven graphics based on the Milkdrop standard.
- Milkdrop Preset Integrations - Supports the loading and rendering of Milkdrop-compatible shader files to achieve specific visual styles.
- WebAssembly Renderers - Provides a WebAssembly-compiled version of the rendering engine to enable high-performance audio visualizations within web browsers.
