Spectral View

input file : active soundfile

When you press the SPECTRAL VIEW button situated on the toolbar (or choose the Spectral view command from the Toolbox menu) DART XP Pro will display a spectral panorama of the signal around the current cursor position. Spectral panorama, often called an evolutionary spectrum as it shows how the signal spectrum evolves in time, is a sequence of spectral graphs corresponding to different time instants. The three-dimensional time-frequency spectral plots can be very helpful in spotting some short-lived disturbances, performing the formant analysis of speech or simply better understanding the nature of the analyzed signals.
