Le Biniou vs Plane9

Le Biniou creates live visuals from audio performances or existing tracks, for artists, composers, VJs, and music fans. The open-source software lists more than 100 plugins for graphic effects, including more than 40 that react to sound. Users can arrange plugins into sequences, save them in banks, or have the software generate sequences in schemes mode. Audio inputs include JACK Audio, ALSA, PulseAudio, Open Sound System, Sndio, audio files, and OSC. Output options include MP4 recording, PNG images, RTMP streaming, and a V4L2 loopback device that can feed compatible video software such as OBS. It also handles live cameras and media types supported by FFmpeg or ImageMagick. A web interface can control a running instance over a network from another computer, tablet, or mobile device. The project lists GNU/Linux, Windows 10 with WSL2, Mac OS, FreeBSD, NetBSD, and OpenBSD among its minimum system requirements. Installation options include Debian and derivative distributions, Arch Linux, GitLab packages, and Flatpak. Le Biniou is free.

Plane9 is a free Windows 3D music visualizer and sound-responsive screensaver. It can run in a standalone window, as a screensaver, or as a VR visualizer, with OpenVR/HTC Vive and Oculus Rift support listed. The software offers 250 scenes that can be combined into more than 10,000 views, plus 39 transition scenes. It reacts to audio from computer sources such as Spotify and iTunes and can analyze sound from recording devices. Multiple monitors are supported, and analysis can use up to 18 speakers. A studio application records videos from the visualizer, and video export is available. Plane9 is listed at free for Windows 7, 8, 8.1 and 10. It requires an OpenGL 3.3-capable graphics card; the FAQ recommends a recent OpenGL 4.0 or newer card. Audio analysis does not work with unprocessed digital audio such as DTS. Commercial use of scenes and generated content requires a commercial-use license.
