AddNoise¶
Add noise to the given data.
This adds Gaussian distributed noise to the given data values. This node can be used to test the behavior of various other nodes in the presence of noise. It can also be used as a workaround when the data is linearly dependent and some algorithms run into numerical issues as a result. The noise level is calibrated only on non-streaming (e.g., calibration) chunks. That is, to use this node in a live setting, you will need to use another node to first buffer up some calibration data (e.g., AccumulateCalibrationData), or to load pre-recorded calibration data from a file (InjectCalibrationData).

Ports/Properties¶
data¶
Data to process.
- verbose name: Data
- default value: None
- port type: DataPort
- value type: Packet (can be None)
- data direction: INOUT
relative_amplitude¶
Relative noise level. This is the scale of the noise relative to the scale of the data.
- verbose name: Relative Amplitude
- default value: 0.01
- port type: FloatPort
- value type: float (can be None)
absolute_amplitude¶
Absolute noise level.
- verbose name: Absolute Amplitude
- default value: 0.0
- port type: FloatPort
- value type: float (can be None)
set_breakpoint¶
Set a breakpoint on this node. If this is enabled, your debugger (if one is attached) will trigger a breakpoint.
- verbose name: Set Breakpoint (Debug Only)
- default value: False
- port type: BoolPort
- value type: bool (can be None)
metadata¶
User-definable meta-data associated with the node. Usually reserved for technical purposes.
- verbose name: Metadata
- default value: {}
- port type: DictPort
- value type: dict (can be None)
