Everything you need to create, analyze, and understand harmonic wave patterns.

Watch epicycles rotate in real-time as they construct complex waveforms through Fourier series.

Analyze frequency components with Fast Fourier Transform and visualize the frequency spectrum.

Apply low-pass, high-pass, band-pass, and notch filters to shape your signals in real-time.

See how complex signals are built from individual sine waves, each with its own frequency and amplitude.

Start with classic waveforms like Square, Sawtooth, Triangle. Export as JSON, CSV, or PNG images.
