Detailed Description

Multi-band parametric equalizer with Minimum and Linear Phase modes.

Combines multiple FilterEngine instances into a single processor. Supports up to MaxBands simultaneous filter bands. Lock-free parameter updates and zero memory allocations in the audio thread (the linear-phase engine, including its recompute scratch, is fully pre-allocated in prepare()).

Threading: prepare() belongs to the setup thread (allocates; never call it concurrently with processing). processBlock()/processSample()/reset() belong to the audio thread. Setters are atomic publications consumed at the next block (or next processSample() call); band configs follow the single-writer pattern (one control thread). Non-finite band fields are replaced with the band's current values. getMagnitudeForFrequencyArray() and getBandConfig() are unsynchronized analysis/UI reads.

Dependencies: Filters.h (FilterEngine), AudioSpec.h, AudioBuffer.h, Biquad.h, DenormalGuard.h, DspMath.h, FFT.h, StateBlob.h.
