Detailed Description

Multi-channel, multi-band equalizer with flexible filter types.

EQ provides a professional multi-band equalizer supporting multiple filter types per band. Each band can be configured independently as a shelving filter, peak/notch filter, or high/low-pass filter. Supports any number of channels.

Key Features:

Configurable number of bands
Multiple filter types per band (lowshelf, highshelf, peak, highpass, lowpass)
Multi-channel support
Independent frequency, Q, and gain per band
Based on high-quality biquad filters

Filter Types:

lowshelf: Boost/cut low frequencies
highshelf: Boost/cut high frequencies
peak: Boost/cut at specific frequency (bell curve)
highpass: Remove frequencies below cutoff
lowpass: Remove frequencies above cutoff

Usage:

EQ equalizer(3); // 3-band EQ
equalizer.setSampleRate(44100.0);
equalizer.setNumChannels(2); // Stereo
 
// Low shelf: boost bass at 100Hz
equalizer.setParams(0, EQ::lowshelf, 100.0f, 0.7f, 3.0f);
 
// Peak: cut at 1kHz
equalizer.setParams(1, EQ::peak, 1000.0f, 2.0f, -6.0f);
 
// High shelf: boost treble at 8kHz
equalizer.setParams(2, EQ::highshelf, 8000.0f, 0.7f, 2.0f);
 
equalizer.process(audioBuffer);
