DetermineVocalisationEndpoints(Double[], Double)

WARNING: calculation of k1 and k2 is faulty. MinDecibelReference should not be used ie k1 = EndpointDetectionConfiguration.SegmentationThresholdK1; See the alternative below

************* PARAMETERS FOR:- ENDPOINT DETECTION of VOCALISATIONS See Lamel et al 1981. They use k1, k2, k3 and k4, minimum pulse length and k1_k2Latency. Here we set k1 = k3, k4 = k2, k1_k2Latency = 0.186s (5 frames) and "minimum pulse length" = 0.075s (2 frames) SEGMENTATION_THRESHOLD_K1 = decibels above the minimum level SEGMENTATION_THRESHOLD_K2 = decibels above the minimum level K1_K2_LATENCY = seconds delay between signal reaching k1 and k2 thresholds VOCAL_DELAY = seconds delay required to separate vocalisations MIN_VOCAL_DURATION = minimum length of energy pulse - do not use this - accept all pulses. SEGMENTATION_THRESHOLD_K1=3.5 SEGMENTATION_THRESHOLD_K2=6.0 K1_K2_LATENCY=0.05 VOCAL_DELAY=0.2.
