Projectm
ProjectM is a cross-platform music visualization library and pixel shader rendering engine. It functions as an audio signal analysis tool that extracts beat and frequency data from audio streams to drive real-time graphical changes.
The engine is built for compatibility with the Milkdrop visualization standard, allowing it to parse and load external preset files to define visual styles. It supports the organization of these presets through playlist-driven management to automate transitions between different visual effects.
The system can be integrated into external host applications as a static or shared library. It also includes a WebAssembly bridge to execute high-performance audio visualizations within web browsers.
