Time/Frequency signal sinusoidality

At each time instant t, a sinusoidality coefficient v(t) is estimated.

This coefficient is obtained by use of the Phase Derived
Sinusoidality measure from SINOLA [Peeters and Rodet, 1999].

For each time/frequency region, the instantaneous frequency is
compared to the frequency measured from spectrum peaks.
If they match, the time/frequency region is said to be sinusoidal.

We have designed a low-cost method to compute v(t)t using
frequency reassignment.
