Detailed Description

Calculates the mean level of the input signal

This feature extracts the mean signal level out of the input signal. After each call to nextSample the time window taken for calculating the mean value is cleared.

Constructor & Destructor Documentation

AudioMeanFeature::AudioMeanFeature (  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.

AudioMeanFeature::AudioMeanFeature (  double *  minval, double *  maxval, double  mean )  [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. mean  The sample value.
