Spectral Flow Detection

• Positive spectral differencing detects a quick increase of energy, as in the case of an attack for instance.

• Negative spectral differencing detects a quick decrease of energy, as in the case of the end of a note.

To trigger the analysis, press Alt + Cmd + M or choose Analysis/Generate Markers.

In the upper pop up menu of the dialogue window, choose Spectral Differencing (positive-negative)

Markers will be displayed across the waveform and sonogram windows.

• Markers are represented at the bottom of the sonogram by a small triangle, with a line crossing the whole waveform and sonogram windows.

• Positive spectral flow markers are pink.

• Negative spectral flow markers are yellow

• A selected marker is bright red.
