Method Detail

getDelay

public int getDelay(FFTDataBlock fftDataBlock,
                    WhistleShape whistle,
                    int whistleChannel,
                    int bearingChannel)

Calculates the delay between a whistle on one channel and another given channel number. Used the whistle contour width and the sweep to calculate only in a very narrow band so that overlapping whistles may simultaneously get bearings calculated.

Parameters:

whistle -

Returns:

a delay in bins or WHISTLE_NODELAY.
