Sound Wave Visualizer
Interactive simulation — adjust parameters and watch the visualization update in real time.
How it works
Live waveform (pressure vs time) and a bar spectrum from your microphone using the Web Audio API. Speak, clap, or play music — peaks in the spectrum show which frequencies carry energy.
Key equations
Bin i ≈ i · (sampleRate / FFT size) Hz up to Nyquist f_N = sampleRate / 2
