Formants and Harmonics Tracking.
Analyzing a signal with the two-layer
model permits separate tracking of the harmonic and formant of
any given point in the spectrogram.
The user clicks on the spectrogram to select a bin and the system
reveals the harmonics and formant "history"
for that bin. Figure 12 b) shows an example of harmonics
tracking for the bin chosen in part
a); c) shows an example of formant tracking for the bin chaosen in
part a).

Watch another example on the following video.
Description
of Video 8.
The video, displays information in five
panels. Panel 1 displays the spectrogram of the signal. Panels
2 and 3 show the harmonics and formants
layers.Panels 4 and 5 display the
harmonics and formants
transformation maps. The user can "click"
anywhere on the spectrogram and then track the
harmonics or formants "history" by selecting
the harmonics tracking button or the formants tracking
button. The tracking results are displayed
on panel 1 and in the correspondent panel for the component
being tracked.

Two Speakers Semi-Supervised Source
Separation.
After modeling the input signal, the
user "clicks" on those regions of the spectrogram that he believes
belong to the speaker that is intended
to be eliminated. The system then masks all neighboring
time-frequency bins with the same prominent
transformation as the one of the selected bin, the bins
remaining in the spectrogram belong
to the other speaker. Figure 13, depicts an instance of this
application. Part a) shows the user
"clicks" on the spectrogram, b) shows where the "clicks" map
into the harmonics transformation map,
and part c) shows the resultant mask.
