🧠 Brainwave Oscillations — Five-Band EEG Waveform Simulator (2D)

Interactive 2D EEG waveform simulator: five real frequency bands — delta (0.5-4 Hz), theta (4-8 Hz), alpha (8-13 Hz), beta (13-30 Hz) and gamma (30-100 Hz) — summed as sine waves into a scrolling composite EEG trace with a live power spectrum. Adjust each band's amplitude or pick a brain-state preset.

⚙ Under the hood

Five real EEG frequency bands — delta (0.5-4 Hz), theta (4-8 Hz), alpha (8-13 Hz), beta (13-30 Hz) and gamma (30-100 Hz) — are each modelled as a cluster of sine-wave oscillators drawn from that band's true physiological frequency range. The bands sum into a scrolling composite EEG trace alongside a live power-spectrum bar chart. Per-band amplitude sliders and relaxed/focused/sleep/meditation presets let you explore how the dominant rhythm shifts across brain states.
