One-Mass - Mono-directional (Harmonic Oscillator)

(make-object 'harmonic-oscillator

• (mass .01)

  (stiffness 15000)

  (freq-loss 100)

  (const-loss 10))

All physical parameters can be numerical values or controllers.

• mass: The mass of the small mass in kg.
• stiffness: The stiffness of the spring in the 'normal direction.
• freq-loss: The usual frequency loss parameter. See the General Object Information for more info.
• const-loss: The usual constant loss parameter. See the General Object Information for more info..

As usual, the freq-loss and const-loss parameters control the rate of decay of the sound. The higher they are, the more damped the sound is.

The 'harmonic-oscillator can be accessed in only one direction: 'normal.

• (make-access my-harmonic-oscillator my-controller 'normal)

A harmonic-oscillator can be tuned to a specific pitch, using the (set-pitch ...) function, by adjusting one of the following physical parameters:

• 'stiffness

• 'mass

For example:

• (setq my-lips (make-object 'harmonic-oscillator

  • (mass 5e-3)

    (stiffness 10)

    (freq-loss 10)

    (const-loss 1) ))

  (set-pitch my-lips 'stiffness 220)
