projectM - Cross-platform Music Visualization Library. Open-source and Milkdrop-compatible.
Experience psychedelic and mesmerizing visuals by transforming music into equations that render into a limitless array of user-contributed visualizations.
projectM is an open-source project that reimplements the esteemed Winamp Milkdrop by Geiss in a more modern, cross-platform reusable library.
Its purpose in life is to read an audio input and to produce mesmerizing visuals, detecting tempo, and rendering advanced equations into a limitless array of user-contributed visualizations.
This repository now only contains the projectM shared/static library. All frontends, plug-ins and other tools were outsourced into separate repositories. If you're not a developer and just look for a download to run projectM visuals on your machine or device, please use one of the links listed below. The releases section in this repository only contains source-code and binary releases of the projectM development libraries and headers, which aren't useful for end users.
The preset files define the visualizations via pixel shaders and Milkdrop-style equations and parameters.
The projectM library does not ship with any presets. The frontends come with varying preset packs which can be found in separate repositories in the projectM repository list:
Included with projectM are the bltc201, Milkdrop 1 and 2, projectM, tryptonaut and yin collections. You can grab these presets here.
You can also download an enormous 41,000 preset pack of presets here (123MB zipped).

At its core projectM is a library, libprojectM. This library is responsible for parsing presets, analyzing audio PCM data with beat detection and FFT, applying the preset to the audio feature data and rendering the resulting output with OpenGL. It can render to a dedicated OpenGL context or a texture.
To get started using projectM in your own projects, please go to the wiki and read the developer documentation available there.
There are some open-source applications that make use of libprojectM which can be found in the projectM organization's repositories and elsewhere.
