Function spectrum_analyzer::scaling::divide_by_N_sqrt

source · 
pub fn divide_by_N_sqrt(fr_val: f32, stats: &SpectrumDataStats) -> f32
Expand description

Like divide_by_N but divides each value by sqrt(N). This is the recommended scaling in the rustfft documentation (but is generally applicable). See https://docs.rs/rustfft/latest/rustfft/#normalization
