Oscilloscope and Audio Visualizer Backdrop

A free, browser-based oscilloscope and audio visualizer. Render an animated waveform scope line, frequency bars, mirrored bars, or a radial scope. It reacts in real time to your microphone, or runs a built-in synthetic demo signal so it works with no mic at all.

Visualizer styles

• Waveform — a classic oscilloscope trace of the audio signal over time.
• Frequency bars — a spectrum analyzer that splits sound into frequency bands.
• Mirrored bars — symmetric spectrum bars, ideal as a lower-third backdrop.
• Radial scope — the spectrum wrapped into a circle.

Features

• Microphone-reactive mode or a no-permission demo mode
• Sensitivity control, six color themes including rainbow
• Fullscreen mode and a hide-controls key
• Microphone audio is analyzed locally in your browser and never transmitted

Perfect for

• Music streams, podcasts, and "now playing" backdrops
• Live-event and presentation visuals
• Sci-fi and synthwave scenes
