-~
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
by default.Attributes

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.
