📊 Audio Visualizer

How Audio Visualization Works

The Web Audio API AnalyserNode captures real-time frequency and time-domain data. This data is drawn to an HTML Canvas as animated bars, waveforms, or spectrograms.

Choose between bar mode (frequency), wave mode (amplitude), or spectrogram (frequency over time). Upload any audio file to see it come alive.

Pro Tips

• Bar mode shows which frequencies are loudest — great for understanding EQ.
• Spectrogram mode reveals hidden details in your audio.
