normalize_sample()

void MayaFlux::Nodes::NodeGraphManager::normalize_sample ( double &  sample, uint32_t  num_nodes  )

private

Normalizes a sample to the range [-1, 1] based on the number of nodes.

Parameters

sample	Reference to the sample value to normalize
num_nodes	Number of nodes in the processing chain

Ensures that the sample value is within the valid range for audio processing.
