MergeTwoWhistleEvents(WhistleEvent, WhistleEvent)

Merges two whistle events into one whistle event. This is useful because a typical bird whistle contains side bands and therefore covers more than one frequency bin. The Whistle detection algorithm detects whistle content in the side bins but puts each bin content in a different event. THis method merges events that belong to the same whistle call.

Declaration
public static WhistleEvent MergeTwoWhistleEvents(WhistleEvent e1, WhistleEvent e2)
Parameters
Type Name Description
WhistleEvent e1

first event.
WhistleEvent e2

second event.
Returns
Type Description
WhistleEvent

a new whistle event .
