Spectral flow detection is done with two type of markers that detect quick energy variations increase or decrease in the signal.
To trigger the analysis, press
In the upper pop up menu of the dialogue window, choose
Markers will be displayed across the waveform and sonogram windows.
As shown by the dialogue window, the accuracy of the analysis entirely depends on the FFT parameters.
Spectral flow markers can be manipulated like manual markers. The number of displayed markers can be controled after the analysis. They can also be partially edited.
