Frequency UnKnown Buzz Machine
Name: Bender
Type: Effect/Distortion
Parameters: Amount, Rate, Inertia
About: Maps the input onto a non-linear function, specifically a sine wave. Amount specifies the extent of the sine wave to be mapped. As everyone knows, the limit of sin x as x approaches zero is x itself, so for a small amount of the sine function the distortion is minimal. When mapping onto several full periods of the wave, the sound is very bent. The effect is implemented using a look up table, which made for some other interesting parameters. Rate is the number of samples in the table that are updated each time the machine does some work. (Updating the whole table every time is too CPU heavy). If this is small and you move the Amount slider a long way, you will be able to hear the discontinuities as the table is updated. To prevent this where it is not wanted, Inertia provides a way of making Amount slide slowly so that these discontinuities don't occur.
