Detailed Description

Phase accumulator producing a [0, 1) ramp for oscillators and LFOs.

Building block for table oscillators, LFOs and modulation carriers (WavetableOscillator, Vibrato, Tremolo, RingModulator). The accumulator and increment live in double internally (framework rule: recursive state in double) so ultra-slow LFO rates neither stall nor drift - a float accumulator freezes completely below ~3e-3 Hz at 96 kHz (the per-sample increment rounds to zero against the phase's ulp) and runs slow LFOs measurably fast (+0.125% at 0.1 Hz). The public API stays in T.

Threading: owner-managed. Not internally thread-safe: call setters and advance() from the owning (audio) thread, or synchronise externally.

Dependencies: DspMath.h (FloatType), AudioSpec.h.
