Free Audio Visualizer Online — Visualize audio with animated waveforms
How to Use Audio Visualizer
Upload an audio file and press play. The canvas shows real-time frequency bars using the Web Audio API AnalyserNode.
Why no visualization?
Press the play button — visualization starts on playback due to browser autoplay policies.
Does it work on mobile?
Yes, though some browsers require a user gesture to activate AudioContext.
