Vinyl Groove & Stylus Physics Simulator (2D)

This 2D simulator follows a turntable stylus as it tracks a spiral groove from the outer edge toward the label, driven by a real constant-angular-velocity model: linear groove speed and groove wavelength both shrink as the radius decreases, exactly the mastering constraint that causes real inner-groove distortion. A live scrolling waveform reconstructs the audio the stylus is reading, and a pitch fader demonstrates the genuine turntable effect of speed changes shifting playback pitch.
