ChirpEvent(Track, Interval<Double>)

Initializes a new instance of the ChirpEvent class.

Declaration
public ChirpEvent(Track chirp, Interval<double> interval)
Parameters
Type Name Description
Track chirp

A chirp track consisting of a sequence of spectral points.
Interval<Double> interval

A min and maximum score used to normalise the track score.
Remarks

MaxScore establishes a scale for the chirp score. Typically the amplitude of track points is decibels. A satisfactory maxScore is 12.0 decibels, since this is a high SNR in enviornmental recordings. The normalised score is a linear conversion from 0 - maxScore to [0, 1].
