Member Function Documentation

process() [1/2]

void sbl::dsp::DcBlocker::process ( float *  buf, uint16_t  frames  )

inline

Process a block of float samples in-place.

Parameters

buf	Sample buffer
frames	Number of samples

Definition at line 41 of file dc_blocker.hpp.

References process().

Here is the call graph for this function:

process() [2/2]

float sbl::dsp::DcBlocker::process ( float  x )

inline

Process one sample through the DC blocker.

Note

All public methods are ISR-safe — bounded computation, no I/O.

Parameters

x	Input sample

Returns

Output with DC removed

Definition at line 29 of file dc_blocker.hpp.

Referenced by process().

Here is the caller graph for this function:

reset()

void sbl::dsp::DcBlocker::reset ( )

inline

Reset filter state to zero.

Definition at line 58 of file dc_blocker.hpp.

set_coefficient()

void sbl::dsp::DcBlocker::set_coefficient ( float  r )

inline

Set the pole coefficient.

Higher values (closer to 1.0) = lower cutoff frequency. Default 0.995 ≈ 16 Hz at 48 kHz sample rate.

Parameters

r	Pole coefficient, typically 0.99-0.999
