Detailed Description

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

Base class for producing band-limited waveforms.

This produces a finite sum of equi-amplitude cosine waves that approach the shape of a periodic impulse train. Due to numerical issues, this generator should not be used for producing very low frequency modulation signals. For that purpose, it is better to use the LFO class.
