object FSinOsc extends ProductReader[FSinOsc] with Serializable
A sine oscillator UGen using a fast approximation. It uses a ringing filter and
is less CPU expensive than SinOsc . However, the amplitude of the wave will
vary with frequency. Generally the amplitude will go down when the frequency
rises and it will go up as if the frequency is lowered.
Warning: In the current implementation, the amplitude can blow up if the
frequency is modulated by certain alternating signals (e.g. abruptly by TRand
).
