Method Description
DifferentialSPL ( double phon0, double phon1 ) : FilterProfile
DifferentialSPL ( double phon0, double phon1, double scale ) : FilterProfile
SPL ( double phon ) : FilterProfile

Create a list of dB SPL equal-loudness values for a given 'phon' loudness (from zero, threshold, to 90)
WeightedVolume ( ISoundObj src ) : double

Calculate the weighted volume of a sound source. NB: this consumes lots of memory for long sources.
WeightedVolume ( ISoundObj src, double dbSPL, double dbSPLBase ) : double

Calculate the weighted volume of a sound source. NB: this consumes lots of memory for long sources.
WeightedVolume1 ( ISoundObj src, double dbSPL, double dbSPLBase ) : double

Calculate the weighted volume of a *single channel* sound source. NB: this consumes lots of memory for long sources.
