Enum Parameter 

pub enum Parameter {
    Bypass,
    EnhancementLevel,
    VoiceGain,
    NoiseGateEnable,
}

Configurable parameters for audio enhancement

Variants

Bypass

Controls whether audio processing is bypassed while preserving algorithmic delay.

When enabled, the input audio passes through unmodified, but the output is still delayed by the same amount as during normal processing. This ensures seamless transitions when toggling enhancement on/off without audible clicks or timing shifts.

Range: 0.0 to 1.0

• 0.0: Enhancement active (normal processing)
• 1.0: Bypass enabled (latency-compensated passthrough)

Default: 0.0

EnhancementLevel

Controls the intensity of speech enhancement processing.

Range: 0.0 to 1.0

• 0.0: Bypass mode - original signal passes through unchanged
• 1.0: Full enhancement - maximum noise reduction but also more audible artifacts

Default: 1.0

VoiceGain

Compensates for perceived volume reduction after noise removal.

Range: 0.1 to 4.0 (linear amplitude multiplier)

• 0.1: Significant volume reduction (-20 dB)
• 1.0: No gain change (0 dB, default)
• 2.0: Double amplitude (+6 dB)
• 4.0: Maximum boost (+12 dB)

Formula: Gain (dB) = 20 × log₁₀(value) Default: 1.0

NoiseGateEnable

Enables/disables a noise gate as a post-processing step, before passing the audio buffer to the model.

Valid values: 0.0 or 1.0

• 0.0: Noise gate disabled
• 1.0: Noise gate enabled

Default: 0.0

Trait Implementations

impl Clone for Parameter

fn clone(&self) -> Parameter

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Parameter

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<Parameter> for Type

fn from(parameter: Parameter) -> Self

Converts to this type from the input type.

impl PartialEq for Parameter

fn eq(&self, other: &Parameter) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Parameter

impl Eq for Parameter

impl StructuralPartialEq for Parameter
