Classes
class	Palette
	Represents a palette used to draw a spectrogram. More...
class	Spectrogram
	This class holds the parameters for a spectrogram and implements its synthesis and generation. More...
class	Filterbank
	Used to divide the frequency domain into suitable intervals. More...
class	LinearFilterbank
	Divides the frequency domain to intervals of constant bandwidth. More...
class	LogFilterbank
	Divides the frequency domain to intervals with variable (logarithmic, constant-Q) bandwidth. More...
Typedefs
typedef std::pair< int, int >	intpair
