Read the project’s introduction
Chat with us on Discord projectM - The most advanced open-source music visualizer 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. Important: This repository only contains libprojectM for use in application development! 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. End-User Applications Important: projectM is currently undergoing heavy development. The available end-user frontends are development previews, which are not feature-complete and may have bugs. Windows Standalone (projectMSDL 2.0 pre-release) Steam (Same as standalone development preview) Windows Store (Old 3.1.12 release) macOS Standalone C++ app pre-release Rust app development preview (signed) Steam (Old 3.1.12 release) Music.app Plugin (currently only available as an unsigned development preview) Brew (Old 3.1.12 release) Linux Standalone (projectMSDL 2.0 pre-release, also available as .deb and .tar.gz) Steam (Same as standalone development preview) Or check your distribution's package manager for a binary release. If it is outdated, please contact the package maintainer, as the projectM development team does not maintain any of the distribution-specific packages. Android Google Play Note: Both the free and paid apps are not created or supported by the projectM developers! If you have technical troubles or other inquiries, please contact the app author via the means provided in the Play Store. Any bug reports in the projectM issue tracker regarding the apps will be closed immediately. Android TV / Google TV ProjectM TV (free, open source; APK download, see the repository for install instructions) Google Play (paid) Note: These apps are not created or supported by the projectM developers, and bug reports in the projectM issue tracker regarding them will be closed.

Click For Demo Videos Presets 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: Base Milkdrop texture pack - Recommended for use with any preset pack! Cream of the Crop Pack - A collection of about 10K presets compiled by Jason Fletcher. Currently, projectM's default preset pack. Classic projectM Presets - A bit over 4K presets shipped with previous versions of projectM. Milkdrop 2 Presets - The original preset collection shipped with Milkdrop and Winamp. En D Presets - About 50 presets created by "En D". 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 130k+ presets from the MegaPack here (4.08GB zipped, incl. textures). Also Featured In Kodi (formerly XBMC) Helix Silverjuke (FOSS Jukebox) VLC Media Player (AKA VideoLAN Client) Reminder: These are all third-party integrations of libprojectM and not developed or supported by the projectM development team. Please report bugs in those applications to their respective developers. Screenshots Architecture Article Building from source See the build guide for instructions on building libprojectM from source, including the full CMake reference, the Emscripten guide for WebAssembly builds, and the developer documentation in the wiki. Using the library 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.

Love projectM! To this day I use it for VJ work and it always gets rave reviews. With the OSS project I've been able to build a great workflow for previewing and picking the best patterns for my aesthetic. If I had one feature request it would be a way to take a set of patterns and an MP3 file and render an output video faster than real-time. It's much easier to use pre-rendered videos and tempo adjust them in VJ software than doing live rendering. Edit: GH Issue discussing rendering: https://github.com/projectM-visualizer/projectm/issues/205
In ProjectM: LGPL Reimplementation of Ryan Geiss' Milkdrop from Winamp/Kodi
For the visualizations - Milkdrop is alive and well as projectM (which sometimes comes bundled with VLC, sometimes not?): https://github.com/projectM-visualizer/projectm Which has a ridiculous level of cross-platform compatibility. I can throw up 3 copies of projectM-pulseaudio on my big 3-monitor work machine and have it listen to any audio sink, I've got it installed on my Android TV and it happily responds to whatever audio's being played, so works with streaming apps and whatnot. There's also thousands and thousands of presets you can add which the community has been adding to since way back when it was still milkdrop, and people have made curated lists like this person's NestDrop: https://thefulldomeblog.com/2020/02/21/nestdrop-presets-coll...
