Struct Biquad 

pub struct Biquad { /* private fields */ }

A biquad section over up to MAX_CHANNELS channels of i16.

Direct form I in f32: y = b0·x + b1·x1 + b2·x2 − a1·y1 − a2·y2; output rounded ties-away and saturated. The design is redone when the input rate changes.

Implementations

impl Biquad

pub fn new(kind: BiquadKind) -> Self

A section of kind; designed on the first block.

pub fn coefficients(&self) -> Coefficients

The coefficients in use (identity until the first block).

Trait Implementations

impl Clone for Biquad

fn clone(&self) -> Biquad

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Biquad

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

Formats the value using the given formatter.

impl Element for Biquad

fn output_format(&self, input: PcmFormat) -> Result<PcmFormat>

The format this element emits for blocks in input, or Err(Unsupported) if it cannot take input at all.

fn process(&mut self, input: PcmBlock<'_>, out: &mut [u8]) -> Result<usize>

Process one block into out, returning the bytes written — a whole number of output frames, possibly zero.

fn reset(&mut self)

Forget all state (filter memories, gains, phases).

fn max_output_bytes(&self, input: PcmFormat, input_bytes: usize) -> usize

Upper bound on the bytes process writes for an input block of input_bytes bytes in input. Defaults to input_bytes (same-size elements); resamplers and channel converters override it.
