Struct knyst::gen::filter::svf::SvfFilter

pub struct SvfFilter { /* private fields */ }

A versatile EQ filter implementation

Implemented based on a technical paper by Andrew Simper, Cytomic, 2013 also available at https://cytomic.com/technical-papers/

Implementations

impl SvfFilter

pub fn new( ty: SvfFilterType, cutoff_freq: Sample, q: Sample, gain_db: Sample ) -> Self

pub fn set_coeffs( &mut self, cutoff: Sample, q: Sample, gain_db: Sample, sample_rate: Sample )

Set the coefficients for the currently set filter type. gain_db is only used for Bell, HighShelf and LowShelf.

pub fn init(&mut self, sample_rate: SampleRate)

pub fn process_sample(&mut self, v0: Sample) -> Sample

pub fn process(&mut self, input: &[Sample], output: &mut [Sample]) -> GenState

impl SvfFilter

pub fn upload(self) -> Handle<SvfFilterHandle>

Upload the Gen to the currently selected Graph and return a handle

Trait Implementations

impl Clone for SvfFilter

fn clone(&self) -> SvfFilter

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Gen for SvfFilter

fn process( &mut self, ctx: GenContext<'_, '_>, resources: &mut Resources ) -> GenState

The input and output buffers are both indexed using [in/out_index][sample_index].

fn num_inputs(&self) -> usize

The number of inputs this Gen takes. Determines how big the input buffer is.

fn num_outputs(&self) -> usize

The number of outputs this Gen produces. Determines how big the output buffer is.

fn input_desc(&self, input: usize) -> &'static str

Return a label for a given input channel index. This sets the label in the Connection API.

fn output_desc(&self, output: usize) -> &'static str

Return a label for a given output channel index. This sets the label in the Connection API.

fn init(&mut self, block_size: usize, sample_rate: Sample, node_id: NodeId)

Initialize buffers etc. Default: noop

fn name(&self) -> &'static str

A name identifying this Gen.
