GetOneFrameTracks(SpectrogramStandard, OneframeTrackParameters, TimeSpan, Double)

A one-frame track sounds like a click. A click is a sharp onset broadband sound of brief duration. Geometrically it is similar to a vertical whistle. THis method averages dB log values incorrectly but it is faster than doing many log conversions. This method is used to find acoustic events and is accurate enough for the purpose.

Declaration

public static (List<EventCommon> Events, double[] Intensity) GetOneFrameTracks(SpectrogramStandard sonogram, OneframeTrackParameters parameters, TimeSpan segmentStartOffset, double decibelThreshold)

Parameters

Type	Name	Description
SpectrogramStandard	sonogram
OneframeTrackParameters	parameters
TimeSpan	segmentStartOffset
Double	decibelThreshold

Returns

Type	Description
(T1, T2)<List<EventCommon>, Double[]>

GetOneFrameTracks(Double[,], Int32, Int32, Double, Double, Double, UnitConverters)

Extracts click type tracks. A click occupies one frame. In a spectrogram it is equivalent to a vertical ridge. A click is a sudden onset event but may have a training echo.

Declaration

public static List<Track> GetOneFrameTracks(double[, ] peaks, int minBin, int maxBin, double minBandwidthHertz, double maxBandwidthHertz, double threshold, UnitConverters converter)

Parameters

Type	Name	Description
Double[,]	peaks	A matrix that identifies the location of sudden onset peaks.
Int32	minBin	Bottom of the frequency band to search.
Int32	maxBin	Top of the frequency band to search.
Double	minBandwidthHertz	Minimum band width spanned by the click event.
Double	maxBandwidthHertz	Maximum band width spanned by the click event.
Double	threshold	The amplitude threshold to qualify as a sudden onset ridge.
UnitConverters	converter	To do the time/freq scale conversions.

Returns

Type	Description
List<Track>	A list of click tracks.
