Class thl::dsp::utils::SineOscillator

class SineOscillator

Sinusoidal oscillator using the coupled-form (magic circle) algorithm.

s1[n+1] = s1[n] + w·s2[n] s2[n+1] = s2[n] - w·s1[n+1]

where w = 2·sin(π·freq/sample_rate). Output is s1 (sine). Initialised with s2 = amplitude so the output ramps up from zero.

Call prepare() before use.
