Spectra is an app for creating 3D art from video and audio on iOS and Mac. It stores parameters such as control values, color palettes, and audio samples in settings files. It comes with built-in presets, video and audio samples to generate art quickly. You can customize the art with your own settings, video, and color palettes. Video frames can be used to generate color palettes for drawing, and the audio is used to modulate line or arc length. The colors pane contains a color palette generator and other features.
