Bezier waveform 2
A Bezier waveform is a collection of Bezier curves. This waveform has 4 control points (aka Vertices) connected by 3 Bezier curves. 8 handles (aka Tangents) - 2 for each vertex - are available to sculpt your waveform.
The FFT of each Bezier waveform is unique like a fingerprint. It has its own sound.
