Detailed Description

Analog-style random modulation: white/pink/brown drift generators.

Header-only C++20 generator of smooth, analog-style random values for modulation. Supports white, pink, and brown noise types.

Features:

• True audio-rate analog drift (continuous 1/f and 1/f^2 filtering).
• Sample-and-Hold LFO behavior with 1-pole smoothing.
• Zero allocations, cache-friendly block processing.
• Lock-free thread safety between GUI and audio threads.
• DC-free denormal mitigation.

Dependencies: AnalogConstants.h, C++20 standard library (<algorithm>, <array>, <atomic>, <chrono>, <cmath>, <cstdint>, , <type_traits>).
