Detailed Description

Represents a subband

This feature represents a subband of the frequency spectrum. The calculation is performed using the FFT algorithm. The feature has to be referenced as "Audio.Band.[n]" where n is a number in the intervall [0; bands]. The maximum number of bands is a global variable defined in the AudioFeatureProvider.

Constructor & Destructor Documentation

AudioBandFeature::AudioBandFeature (  double *  minval, double *  maxval )  [inline, protected]

Feature constructor This constructor initializes the feature with a random value and should thus only be used for creating e.g. prototypes of points in a clustering space. For creating a specific sample of a feature, the second constructor should be used. Parameters: minval  A reference to a static variable (it must be same for all created objects of _one_ feature) for persistantly storing the minimum value. maxval  A reference to a static variable (it must be same for all created objects of _one_ feature) for persistantly storing the maximum value.

AudioBandFeature::AudioBandFeature (  double *  minval, double *  maxval, double  val )  [inline, protected]

Sample constructor This constructor initializes the feature with a specific value and should thus be used for samples. Parameters: minval  A reference to a static variable (it must be same for all created objects of _one_ feature) for persistantly storing the minimum value. maxval  A reference to a static variable (it must be same for all created objects of _one_ feature) for persistantly storing the maximum value. val  The sample value.

virtual const string AudioBandFeature::getName (   )  const [inline, virtual]

Query a features name Returns: Name of the Feature in the format "Featureprovider.Feature" Reimplemented from NumericalContinuousFeature.

string AudioBandFeature::toString (   )  const [virtual]

This is only for testing. Reimplemented from NumericalContinuousFeature.
