The Atan Node computes the inverse tangent for every sample. It’s the inverse of the Tan Node, and is useful for mapping an unbounded control signal into a bounded range — atan compresses any finite input into that range, making it a smooth nonlinear clamp/squash. The output is always in the range (-π/2, π/2).
Inputs
Audio/Control Input
The signal to compute the arctangent from.
If your source signal has more than 1 channel, the arctangent is computed independently for each channel.
Outputs
Audio/Control Output
The computed inverse tangent of the Audio/Control Input, in radians.
The channel count is the same as the input channel count. This output supports constant folding if the Audio/Control Input is constant.
