Enum SpectrumPreproc 

#[non_exhaustive]
pub enum SpectrumPreproc {
    None,
    Gaussian {
        sigma: f64,
    },
    Median {
        window: usize,
    },
}

Optional smoothing applied to the magnitude spectrum prior to peak detection. Has no effect on the filter bank itself — only on which peaks the BoundaryDetection sees.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

None

No preprocessing.

Gaussian

Discrete Gaussian convolution with standard deviation sigma, measured in spectrum-sample units. sigma > 0.

Fields

sigma: f64

Standard deviation of the Gaussian kernel.

Median

Odd-window median filter. window ≥ 3 and window is rounded up to the next odd integer if even.

Fields

window: usize

Median-filter window length in samples.
