In this tutorial I’ll show you how to use a Sound Effector to drive the Luminance Brightness of a material. We will set it up so that everything is animated without keyframes and driven using the Sample Effector found in Xpresso. Below is an example of what the end product will look like. I will show you how to set up Xpresso to pull the audio track from the Sound Effector and input it into the materials Luminance Brightness so that when the animation plays, the brightness reacts to the sound.
When watching this tutorial you will notice that I mention the audio clip requirements in order for it to be used with the Sound Effector. Here are the requirements for the audio: Format: .WAV or .AIF
Sample Rate: 11,22 kHz and 44 kHz
Sample Type: 8 bit and 16 bit
Audio Codec: Uncompressed
When you’re creating or working with your audio files, it’s a good thing to keep in mind that Cinema 4D will playback your audio one second of sound per one second of animation. So regardless of the frame rate, your sound will still be timed how it was created or edited.
Be sure to post the links to your work showing us what you were able to create using these techniques.
