Struct VadContext 

pub struct VadContext {
    pub is_silence: bool,
}

Optional VAD context for intelligent DC bias updates.

When provided, DC bias is only updated during silence periods, avoiding speech distortion. This leverages the VAD engine for progressive enhancement without tight coupling.

Example

use speech_prep::preprocessing::{DcHighPassFilter, PreprocessingConfig, VadContext};

let mut filter = DcHighPassFilter::new(PreprocessingConfig::default())?;
let samples = vec![0.0; 1600];

// Without VAD (always update DC bias)
let output1 = filter.process(&samples, None)?;

// With VAD (update only during silence)
let vad_ctx = VadContext { is_silence: true };
let output2 = filter.process(&samples, Some(&vad_ctx))?;

Fields

is_silence: bool

True if the current audio is classified as silence.

When true, DC bias tracking is updated. When false, DC bias is frozen (preserves speech quality).
