Struct VhsOptions 

pub struct VhsOptions {
    pub alpha: f32,
    pub beta: f32,
    pub dewind_cutoff: f32,
    pub harmonics: usize,
    pub deess_threshold: f32,
    pub normalize_lufs: Option<f32>,
}

Knobs for vhs_restore. Defaults match the measured tape chain.

Fields

alpha: f32

Spectral-subtraction over-subtraction factor (1 = gentle, 6 = aggressive).

Default 2.0. Alpha 3 with coherent subtraction gates pauses to near-silence.

beta: f32

Spectral floor as a fraction of the input magnitude.

dewind_cutoff: f32

High-pass cutoff for rumble / wind (Hz).

harmonics: usize

How many mains harmonics to evaluate (each is gated on standing out).

deess_threshold: f32

Multiband de-ess threshold: dB above each band’s running average.

Typical values are 3–6. This is not the single-band deesser HF/broadband-ratio default (−24); that value compresses every frame and takes down the whole region above 4 kHz.

normalize_lufs: Option<f32>

Optional EBU R128 target (LUFS). None leaves loudness alone.

Trait Implementations

impl Default for VhsOptions

fn default() -> Self

Returns the “default value” for a type.
