Sound Texture
Updated: 12 May 2025
Generates an image based on the sound an audio source.
Sound 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 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 generated image as an overlay in the viewport.
- Off : No preview is generated.
- RGBA : Preview the image blended with alpha in the viewport.
- RGB : Preview the colour channels in the viewport.
- Alpha : Preview the alpha channel in the viewport.
- PIP : Preview the image blended with alpha in the viewport, in a smaller picture in picture display, on top of the existing content.
Width
The resolution of the generated image horizontally.
Height
The resolution of the generated image vertically.
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 run seamlessly at the end of the composition.
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 generated image blends with the project, depending on the compositing mode chosen.
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 amount is ignored.
- Blend : The generator RGBA values have matching alpha channels.
- Additive : Adds the generator colour values to the input colour values, brightening the final image.
- Subtractive : Subtracts the generator colour values from the input colour values, darkening the final image.
- Multiply : Multiplies the generator colour with the input colour. The resulting image is always darker.
- Max : Compares the generator and the input colours, and outputs the lightest value for each channel.
- Min : Compares the generator and the input colours, and outputs the darkest value for each channel.
- Screen : Multiplies the inverse of the generator and input colours. The result is a lighter image, similar to projecting two images onto the same screen.
- Light : Outputs the lighter of the two input colours for each pixel, brightening the overall image.
- 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.
