Audio Input

The Audio Input is used to induce vibration based on an audio signal in each Body object that is connected to it via an Exciter Link. The orientation of the Audio Input controls the direction in which each Body is vibrated. The audio signal can come from an external input source (e.g., your computer's microphone) or from an internal source by connecting one or more Mics via Delay Lines. For more info, see the section on Delay Lines.

Audio Input Properties#

• Ext. Input: The external audio input channel to use for this Audio Input Exciter. If a stereo input is chosen, the stereo channels will be summed into a mono channel. If "<none>" is selected, then the Audio Input Exciter will ignore external signals and will only receive signals from internal Delay Lines.
• Gain: The amount of gain that will be applied to the audio signal before it is applied as a directional force to connected Body objects.
• Delay: The duration for which the audio signal will be delayed before being applied as a directional force to connected Body objects. This is applied to both external audio signals and Delay Line signals. Note that Delay Lines each have their own delay parameter, which is additive to this one.
• MIDI Note Gate: If enabled, the audio signal will be muted except when the associated MIDI note is played, and an envelope will be applied. When this is enabled, the envelope parameters below appear.
• Envelope Attack: When the MIDI note is pressed, this is the duration it takes for the envelope to increase from minimum to maximum gain.
• Envelope Decay: After the attack phase of the envelope is finished, this is the duration it takes for the envelope to drop from full gain to sustain gain.
• Envelope Sustain: After the decay phase of the envelope is finished, this is the fraction of maximum gain that the envelope will sustain.
• Envelope Release: When the MIDI note is released, this is the duration it takes for the envelope to decrease from sustain gain to minimum gain.
