Sound Wave Visualizer

This interactive simulator explores Sound Wave Visualizer in Waves & Sound. Real-time waveform and frequency spectrum from microphone. Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.

Who it's for: Suited to beginners and first exposure to the topic. Typical context: Waves & Sound.

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
