zerox
Detect zero crossings
Description
The zerox object detects when incoming values cross the zero point in either direction from one value to the next. If a crossing is detected, it outputs a value of 1, else it outputs a zero.
Arguments
x [number]
The input that is analyzed for zero-crossings.
Inlets
x [number]
The input that is analyzed for zero-crossings.
Outlets
out1 [number]
Outputs a 0 when the last two received values do not cross the zero point or a 1 when they do.Fixed Attributes
These attributes must be set in the object box and determine the behavior of the object at runtime.
hot [bool] (default: false)
Trigger computation on all inlets.
Dynamic Attributes
These attributes can be modified in the code during execution using the set object
reset [bang] (default: 0)
Banging this attribute will reset the object to its default state.
x [number]
The input that is analyzed for zero-crossings.
