Struct LowPass 

pub struct LowPass { /* private fields */ }

3rd Order Butterworth Low Pass Filter with resonance.

Implementations

impl LowPass

pub fn new(fc: MathT, r: MathT) -> LowPass

Creates a new low pass from the given cutoff frequency and resonance values.

Parameters

• fc - The cutoff frequency.
• r - The resonance of the filter. Value should be in the range [0,1]. If the value falls out of that range it is clamped to the closer value.

pub fn get_central_frequency(&self) -> MathT

Returns the central frequency of the filter.

pub fn set_central_frequency(&mut self, fc: MathT)

Sets the central frequency of the filter.

pub fn get_resonance(&self) -> MathT

Returns the resonance of the filter.

pub fn set_resonance(&mut self, r: MathT)

Sets the resonance of the filter.

Trait Implementations

impl Clone for LowPass

fn clone(&self) -> Self

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

Performs copy-assignment from source.

impl Modifier for LowPass

fn process(&mut self, x: SampleT) -> SampleT
