Audio

Power animation of points with an audio file. Audio supports uncompressed WAV and AIFF files. The sample rate is automatically detected.

Audio Node

Mode: Determines what part of the audio file is used to drive the animation. Spectrum uses its EQ frequencies while Average uses its average volume.
Output Mode: Determines the method used to apply the results to the animation. Normal adds the results to the incoming channel while Multiply applies the result as a factor.
Filename: Specifies the source audio file.
Amplifier: Amplifies the output value.

Frequency Graph

The frequency graph controls which frequencies are used to get results. The graph spans the size of your network so by identifying the bass, for example, you can draw a graph around it to isolate that frequency.

Enable X, Enable Y, Enable Z: Control which axes are driven by the audio file.
Lower Threshold, Upper Threshold: Determines the minimum and maximum amplifier values (any input lower or higher than the threshold is ignored).

Strength

Strength: Fades the node's effect for all the objects at the same time.
Random Strength: Smoothly fades the node's effect on all the objects in a random order.
Step Strength: Turns the node's effect off one object at a time.
Strength Map: Determines the input file (2D texture, animated texture, etc) that controls the shape of this node's effect.
Map Projection Axis: Determines the axis along which the Strength Map is projected.
Map Helper: Displays the object being used to interactively place the Strength Map in the scene. You can right-click the field to create a new helper object (a plane) if none exists. You can also middle-drag a mesh into this field or right-click to connect a selected mesh. If a mesh is already connected, you can also right-click to break its connection or show it in the Outliner.
Note: For the best results, assign the same texture to both the Strength Map and the Map Helper (this automatically happens when creating a new helper object).

Time

Time: Displays the current frame.
Time Offset: Offsets the sound from the beginning of the timeline.
Time Step Average: Average volumes will be passed down the line. Default is on.
