jAudioFeatureExtractor.AudioFeatures.AreaMoments
public class AreaMoments
This class implements 2D statistical methods of moments as implemented by Fujinaga (1997). The number of consecutive windows that one can edit across is an editable property. Furthermore, this classes window property is affected by global window size changes.

public double[] extractFeature(double[] samples, double sampling_rate, double[][] other_feature_values) throws java.lang.Exception
FeatureExtractor
内の extractFeature
samples
- The samples to extract the feature from.sampling_rate
- The sampling rate that the samples are encoded with.other_feature_values
- The values of other features that are needed to calculate this
value. The order and offsets of these features must be the
same as those returned by this class's getDependencies and
getDependencyOffsets methods respectively. The first indice
indicates the feature/window and the second indicates the
value.
java.lang.Exception
- Throws an informative exception if the feature cannot be
calculated.public void setWindow(int n) throws java.lang.Exception
FeatureExtractor
内の setWindow
n
- the number of windows of offset to be used in calculating this
feature

内の getElement
index
- which of AreaMoment's attributes should be edited.
