Detailed Description

DC blocking filter (high-pass filter) to remove DC offset.

DCBlocker implements a simple first-order high-pass filter to remove DC offset from audio signals. This is useful after certain DSP operations (like waveshaping or oscillators) that may introduce DC bias.

Key Features:

Configurable cutoff frequency (default 10 Hz)
First-order IIR filter
Very low CPU usage
Reset for clearing filter state

Usage:

DCBlocker blocker;
blocker.setSampleRate(44100.0f);
blocker.setCutoff(10.0f); // Block below 10 Hz
 
// Per-sample processing
float output = blocker.process(input);
