  • Karplus Oscillator Model

  • Description: Karplus-Strong is a sound synthesis method developed by Kevin Karplus and Alex Strong at Stanford University. It creates realistic drum and plucked-string sounds by looping a short noise burst through a filtered delay. This physical modeling approach recreates an instrument's physical characteristics digitally, such as string bow position, striking force, and the materials' diffusion and damping.
  • In physical modeling, an exciter creates vibrations in a resonator. The exciter can be a bow or a strike, and the resonator can emulate many instrument shapes.
  • Bow: Sets how much bow is added on top of the strike. Bowing creates a continuous tone, while a strike alone creates a decaying tone.
  • Position: Controls where and how hard the resonator is struck. It does not affect the bowed part of the sound.
  • Decay: Sets the resonator's resonance by controlling its decay.
