dmn Visualiser vs projectM

dmn Visualiser turns music into real-time 3D visuals in a web browser, with more than 75 audio-reactive scenes. It analyzes audio locally for frequency bands, beats, BPM, pitch, and musical mood. Audio can come from system audio, browser tabs, audio devices, microphones, or file playback. The maker lists Spotify, Apple Music, DJ Pro, Traktor, Serato, and SoundCloud as compatible sources. Users can let the visualiser choose scenes, switch scenes manually, view them full-screen, and use Dampen mode oriented toward photosensitivity. The maker says GPU-accelerated rendering runs at 60fps and filters heavy shaders on lower-end devices. It says audio processing stays in the browser and audio data does not leave the device; network requests are for authentication and payment. Chrome and Edge support system-audio and tab capture, while Firefox and Safari render visuals but cannot capture audio from other apps. On phones, users can load files; Android users can also use a microphone. The free preview has five sessions, five minutes each, and five scenes. Full access costs $1, paid once.

projectM is an open-source music visualizer that turns audio input into visuals in real time. Its libprojectM library is intended for application development and reimplements Winamp MilkDrop, including support for user-contributed visualizations. The library analyzes PCM audio with beat detection and FFT, then renders visuals using OpenGL. Preset files define looks through pixel shaders and MilkDrop-style equations, but libprojectM does not include presets. The projectMSDL desktop frontend listens to audio input and produces visuals; standalone options are listed for Windows, macOS, and Linux. The library documentation lists builds for Windows, Linux, macOS, iOS, Android, and WebGL/WASM. The core library is licensed under the GNU Lesser General Public License 2.1. projectM is free and open source. Its available end-user frontends are development previews that may be incomplete or contain bugs, while Android apps linked by the project are not created or supported by projectM developers. Third-party integrations including Kodi, Silverjuke, and VLC are supported by their respective developers, not the projectM team.
