Detailed Description

template<class Tv = double, class Ts = Synced>
class gam::SineR< Tv, Ts >

Sine oscillator based on an efficient recursion equation.

This oscillator is based on a recursion equation requiring only one multiply and add per sample computation. While calculation is fast, frequency and phase updates are rather expensive and 64-bit precision is required to prevent growing or decaying in amplitude over time. This generator is ideal in situations where a stationary sinusoid is all that is required, e.g. a grain or modulator.
