Summary
Fosfora turns computer audio into live visuals synchronized to the beat, for music visualization and live performance. It includes 56 audio-reactive effects, such as shaders, particle simulations, and lattice effects. Users can stack up to eight layers, reorder them, and select from 13 blend modes. Its audio analysis tracks 83 features 86 times per second, including beat, tempo, key, percussive and harmonic content, and drops. Parameters can be controlled with MIDI, OSC, or a phone or tablet browser used as a touch surface. Layers can draw on images, GIFs, video files, webcam input, photos, or depth maps. Output options include NDI, Spout on Windows, Syphon on macOS, a Linux virtual camera, and file recording; the project names Resolume, VDMX, OBS, and TouchDesigner as compatible software. Presets store layer stacks, while scenes arrange presets into cue lists. Fosfora is free, needs no account, and is available for Linux, macOS, and Windows. Linux and Windows require Vulkan-capable graphics; macOS requires Metal.
