What Plane9 is
Plane9 is a free Windows application that turns sound into animated 3D visuals. It can run in a standalone window, act as a screensaver, or operate as a VR visualizer. The software includes 250 scenes that can be combined into more than 10,000 views, plus 39 transition scenes. Audio can come from computer sources such as Spotify and iTunes, or from recording devices. Plane9 supports multiple monitors and can analyze sound from as many as 18 speakers. Its download page lists OpenVR/HTC Vive and Oculus Rift support. A studio application records videos from the visualizer, and video export is available. The minimum graphics requirement is OpenGL 3.3, while the FAQ recommends a recent OpenGL 4.0 or newer graphics card. Audio analysis does not work with unprocessed digital audio such as DTS. Anonymous usage reports and crash reports are optional.
