## What it is
projectM is an open-source, cross-platform C++ library that renders real-time music visualizations, reimplementing Winamp's MilkDrop. This repository contains libprojectM, the core library for embedding audio-reactive visuals into applications.

## Use cases
- add music visualizations to a media player app
- render audio-reactive graphics in a game or app
- play MilkDrop preset visualizations cross-platform
- embed a music visualizer in a mobile app
- create psychedelic visuals from live audio input

## When to choose
- you need a reusable library to embed audio-reactive visuals in your own application
- you want MilkDrop preset compatibility on modern platforms
- you need cross-platform support including mobile and web

## When to avoid
- you just want a ready-to-run visualizer app for end users - use the separate frontend projects
- you need non-audio-driven generative visuals
- you require a JavaScript-only solution

## Facets
- artifact type: library
- maturity: active
- function: audio-processing, graphics, animation
- domain: media, graphics, cross-platform
- platform: cross-platform, windows, wasm
- tags: music-visualizer, milkdrop-compatible, opengl, real-time-rendering, audio-reactive, audio, linux, macos, android
