The tremolo effect is probably one of the most ancient effects,
66
originated in the earliest days of the history of studio recording. It
67
lost some of its popularity over time (and with the emerge of more
68
exciting digital effects), but you still hear this effect on newer
69
recordings from time to time.

This plugin sounds good mainly on acoustic or electric guitar tracks,
88
and should be used only occasionally. To create a "floating" effect,
89
set the frequency value to 3-6 Hz. To create a more intensive effect,
90
set it to 8-15 Hz (recommended mostly on electric guitar tracks). The
91
depth should be probably set somewhere between 50% and 90%. If you
92
feel that the overall loudness of the track decreases when this effect
93
is applied, you can compensate this by setting the "Gain" control.

The sine function is implemented via a sine table, which is computed
120
when the host loads the plugin library. This sort of implementation
121
was necessary because calling <code>sinf()</code> for every sample
122
proved to be way too expensive -- that very call itself doubled the
