Welcome to the BeatViewer wiki!
BeatViewer is a Python program that analyzes an audio stream, extracts onsets, tempo and beats, and creates visuals from them in real time. Feature extraction relies on state-of-the-art beat tracking algorithms. Visuals are rendered via Pygame or external programs such as OBS Studio or any WebSocket client.
For a detailed narration of the birth of the project, watch the associated video (in French, English subtitles are coming).
