This video will show how to simulate the look of a vibrating speaker diaphragm by using Motion FX inside Houdini. We use a lattice to isolate and move the speaker diaphragm geometry and then we apply a Motion FX CHOP on the Translate X value of the lattice, to fake the look of the diaphragm vibrating. We observe the difference between putting down a wave, noise and also importing an audio clip so that the motion of the lattice corresponds to the music. To do this, we go inside the Motion FX CHOP and put down a File node and a Math node. We also need to change the settings of the Audio Panel or else we won't be able to see or hear the playback of the audio with the CHOP animation.
