The Fractional Node converts a signal (each sample in a signal) to its fractional part. That is, a value of 1.4 will become 0.4, and a value of -2.3 will become -0.3.
One of its uses is combining it with something like a Timer Node to create a perfect, non-bandlimited sawtooth signal. It’s also useful for constraining a signal into the -1 to 1 range.
Inputs
Audio/Control Input
The signal to convert.
You’ll typically use the Fractional Node with control signals to create more advance control automation setups. However, it supports audio signals too. Audio signals are typically between -1 and 1, in which case the Fractional Node doesn’t make any changes to the output. However, when the signal is outside this range, it adds a very strong distortion effect.
If you use a non-mono signal, the fractional is computed for each channel individually.
Outputs
Audio/Control Output
The fractional part of the input signal, which is always between -1 and 1 (inclusive). If the input signal is 0 (or nothing is connected), the output is also 0.
The channel count of this output is always the same as the input channel count.
