-~
Description
Use the -~ object to perform signal subtraction (to output a signal which is the difference between two signals).
Examples
Negative DC offset... Subtraction used to invert a signal before adding it in
Arguments
initial-subtraction-value [number]
Optional
Sets an initial amount to subtract from the signal coming into the left inlet. If a signal is connected to the right inlet, the argument is overidden. If no argument is present, and no signal is connected to the right inlet, the initial value is 0 by default.

Arguments
input
[int]
In left inlet: Subtracts the signal coming into the right inlet from this value. If a signal is connected to both left and right inlets, a float or int connected to either inlet will be ignored.
In right inlet: An amount to subtract from the signal coming into the left inlet. If a signal is connected to both left and right inlets, a float or int connected to either inlet will be ignored.
In right inlet: An amount to subtract from the signal coming into the left inlet. If a signal is connected to both left and right inlets, a float or int connected to either inlet will be ignored.
float
Arguments
input
[float]
In left inlet: Subtracts the signal coming into the right inlet from this value. If a signal is connected to both left and right inlets, a float or int connected to either inlet will be ignored.
In right inlet: An amount to subtract from the signal coming into the left inlet. If a signal is connected to both left and right inlets, a float or int connected to either inlet will be ignored.
In right inlet: An amount to subtract from the signal coming into the left inlet. If a signal is connected to both left and right inlets, a float or int connected to either inlet will be ignored.
signal
In left inlet: The signal coming into the right inlet or a constant value received in the right inlet is subtracted from this signal. All signal inputs to a single inlet are summed. If a signal and number are both sent to the left inlet, the specified operation will be performed with those values.
In right inlet: The signal is subtracted from the signal coming into the left inlet, or a constant value received in the left inlet. All signal inputs to a single inlet are summed.
In right inlet: The signal is subtracted from the signal coming into the left inlet, or a constant value received in the left inlet. All signal inputs to a single inlet are summed.
Output
signal
The difference between the two inputs.
