FFT Texture
Generates an image based on the sound an audio source.
FFT Texture
Method #
This node generates a texture based on the sound from either a selected or input audio source. The generated texture can then be modified using the same Attack/Decay tools as a sound modifier.
This node can be connected to any node which accepts an image input.
Parameters
These properties control the 3D transforms of the node. Transforms will generally be inherited by child nodes, although they can be ignored through the Inherit Transform Channels attributes.
Control the inheritance of the transforms from the parent.
These properties control the core behaviours of the node.
Parameter Details Active Enables or disables the effect. Disabling the effect means it will no longer compute, so disabling a node when not in use can improve performance.
Preview In Viewport Preview the effect blended with alpha in the viewport.
Width The resolution of the effect along its width.
Height The resolution of the effect along its height.
Update Time Mode How the generator updates with relation to the timecode.
- Locked To Timecode : The generator animations are locked to the timecode and the same time will always yield the same result.
- Running / Loopable : The generator animations are disconnected from the timecode and will loop seamlessly at the end of the layer.
Sound Sound file used to drive the effect.
Looping Control whether the sound loops once it ends
Channel Which audio channel is used.
Band EQ Selects and weights the frequency bands to be used from the sound file.
Time Offset Offset the time the clones are modified from the time the waveform is at.
Change Threshold Changes the threshold for what counts toward the effect.
Attack Controls the initial time between the current values to the peak.
Decay Controls the time between the peak to the sustain level.
Min Value Acts as a minimum threshold for extracting a range of values from the waveform.
Max Value Acts as a maximum threshold for extracting a range of values from the waveform.
Max Clamp A maximum value which values will be clamped if they go above.
Spikiness Accentuates peaks in the waveform so they are sharper.
Scale How much the output values are scaled.
Offset Offset all values output by the texture.
Smoothness How much smoothing is applied between differing values.
Decay Buffer Size Size of the buffer used for sourcing the decay
Falloff Range Range in which the sounds data will be tracked.
Waveform Visualises the waveform of of the sound.
These properties control how the generators are coloured and blended with other images.
Parameter Details Colour Change the colour of the generated image.
Blend Amount The amount the generator is blended with the output.
Blend Mode Choose how the image blends with the scene. See Blend Modes for details.
- Solid : The generator is solid, with a filled alpha channel.
- Blend : The generator RGBA values have matching alpha channels.
- Pre-Mul Blend : The RGB values are solid white, and the generator colours are stored in the alpha channel alpha. Usually gives the best results for colour blending.
