Live Audio Reactive Screensaver
The Live Audio Reactive screensaver shows real bars and waveforms driven live by your actual microphone input, with your permission. It is free, runs in your browser, and ESC exits.
How the Live Audio Reactive screensaver works
After you click to allow it, the saver reads real live audio from your microphone using the Web Audio API.
A real frequency analysis (FFT) drives a bank of bars, and real waveform samples drive a scrolling trace.
All processing happens locally in your browser — no audio is ever recorded, saved, or sent anywhere.
The microphone is released the moment you leave the saver.
A worked example
Clap once and a real sharp spike ripples across the bars and waveform instantly, exactly matching the real sound just picked up by your microphone.
