Sound Modifier
Generates a modifier value based on the waveform of an audio source.
Sound Modifier
Method #
This node outputs a modifier value based on the waveform of an audio file or a live captured audio input. The waveform is processed using a set of parameters, allowing for greater control over how the sound is interpreted.
The output is a numeric value that can be further processed with other modifiers, or directly connected to a parameter in another node, using the operation method selected.
Parameters
These properties control the core behaviours of the node.
Parameter Details
Current Value Shows the current value of the effect. Cannot be directly changed.
Blend Amount The amount to blend the input modifier’s value with it’s new value.
Sound Sound file used for the modifier.
Looping Controls whether the sound loops across timeline loops or resets. Only functions if a sound is selected within this node and a sound source isn’t connected to the Sound input.
Operation The operation to be performed on the targeted parameter.
- Add : Adds to the parameter value.
- Subtract : Subtracts from the parameter value.
- Multiply : Multiplies the parameter value.
- Replace : Replaces the parameter value.
Restore Values Toggle whether the values restore to 0. If unchecked, generated values incrementally add to the modifier value.
Frequency Band Sets the Band EQ to one of the given presets.
Band EQ Selects and weights the frequency bands to be used from the sound file.
Time Offset Offsets the time the value is modified from the time the waveform is played.
Change Threshold Changes the threshold for what counts toward the modifier.
Attack Controls the initial time between the current value 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 audio feed.
Max Value Acts as a maximum threshold for extracting a range of values from the audio feed.
Max Clamp Clamps the result.
Spikiness Accentuates peaks in the waveform so they are sharper.
Scale Adjust the scale/range of the modifier.
Offset Offset the waveform.
Smoothness Adjust the amount of smoothing to applied to the output value.
Waveform A visual representation of the output of the node.
