class FMOD::Effects::Tremolo
This unit produces a tremolo / chopper effect on the sound.
The tremolo effect varies the amplitude of a sound. Depending on the settings, this unit can produce a tremolo, chopper or auto-pan effect.
The shape of the LFO (low freq. oscillator) can morphed between sine, triangle and sawtooth waves using the {#shape} and {#skew} parameters.
{#duty} and {#square} are useful for a chopper-type effect where the first controls the on-time duration and second controls the flatness of the envelope.
{#spread} varies the LFO phase between channels to get an auto-pan effect. This works best with a sine shape LFO.
The LFO can be synchronized using the {#phase} parameter which sets its instantaneous phase.
