Struct DcBlocker 

pub struct DcBlocker { /* private fields */ }

Per-channel DC blocker using a 1-pole high-pass filter.

Default cutoff is 5 Hz — low enough to preserve all audible content while effectively removing DC offset from nonlinear processors.

Implementations

impl DcBlocker

pub fn new(channels: usize, sample_rate: u32, cutoff_hz: f32) -> Self

Create a new DC blocker.

cutoff_hz: Corner frequency (typically 3-10 Hz).

pub fn new_default(channels: usize, sample_rate: u32) -> Self

Create with default 5 Hz cutoff.

pub fn process_sample(&mut self, sample: f32, channel: usize) -> f32

Process a single sample for one channel.

y[n] = x[n] - x[n-1] + R * y[n-1]

pub fn process_block_interleaved( &mut self, buffer: &mut [f32], channels: usize, num_frames: usize, )

Process a block of interleaved audio in-place.

buffer: Interleaved samples [ch0_f0, ch1_f0, ch0_f1, ch1_f1, ...] channels: Number of interleaved channels. num_frames: Number of frames (samples per channel).

pub fn reset(&mut self)

Reset all filter state to zero.

pub fn set_sample_rate(&mut self, sample_rate: u32, cutoff_hz: f32)

Update sample rate (recalculates coefficient).

pub fn set_channels(&mut self, channels: usize)

Update channel count (re-allocates state vectors).
