Struct DcBlock 

pub struct DcBlock { /* private fields */ }

y[n] = x[n] - x[n-1] + r·y[n-1], per channel, in f32.

r = 1 - 2π·fc/fs; the default corner is 20 Hz. The response at fc is −3 dB; above ~5·fc the gain is within 1 % of unity. State is two floats per channel. Output is rounded (ties away from zero) and saturated.

Implementations

impl DcBlock

pub fn new() -> Self

A blocker with a 20 Hz corner; the pole is set from the first block’s rate.

pub fn with_corner(corner_hz: f32) -> Self

A blocker with the given corner frequency.

pub fn pole(corner_hz: f32, rate: u32) -> f32

The pole radius r for rate.

Trait Implementations

impl Clone for DcBlock

fn clone(&self) -> DcBlock

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DcBlock

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

Formats the value using the given formatter.

impl Default for DcBlock

fn default() -> Self

Returns the “default value” for a type.

impl Element for DcBlock

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.
