Extracts tones from a signal and returns their frequency, amplitude, and phase.
Source of the signal and spectrum to export.
This input accepts an array of enums if signal is an array of waveforms.
Name | Description |
---|---|
none | Uses the fastest computation. |
input signal | Exports the input signal only. |
detected signal | Exports a multiple tone. |
residual signal | Exports a signal minus the tone. |
Default: none
Minimum amplitude that each tone must exceed.
This input accepts an array of double-precision floating-point numbers if signal is an array of waveforms.
Default: 0.001
Maximum number of tones that this node extracts. This input must be greater than 0.
This input accepts an array of 32-bit signed integers if signal is an array of waveforms.
Default: 4
The sorting order of the tones that this node extracts.
Name | Description |
---|---|
increasing frequency | Sorts the tones by increasing frequency. |
decreasing amplitude | Sorts the tones by decreasing amplitude. |
Default: increasing frequency
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
Spectrum of the exported signal.
This output can return a cluster or a 1D array of clusters.
Start frequency, in Hz, of the spectrum.
Frequency resolution, in Hz, of the spectrum.
Computed spectrum.
Frequency, in Hz, of each detected tone.
This output can return a 1D array of double-precision, floating-point numbers or a 1D array of clusters.
Phase, in degrees, of each detected tone.
This output can return a 1D array of double-precision, floating-point numbers or a 1D array of clusters.
