Detailed Description

template<class Tv = gam::real, class Ts = Synced>
class gam::Sine< Tv, Ts >

Computed sine wave oscillator.

This oscillator uses a 7th order Taylor series approximation to compute sine values. Computation time is about as much as a linearly-interpolating table lookup. In most cases, Taylor series are also more spectrally pure than table lookup methods since the distortion arises as harmonics.
