Inheritance diagram for MelFilter:

List of all members.

Public Member Functions
	MelFilter ()
	Default constructor : does nothing.
	~MelFilter ()
	Destructor : does nothing.
void	transform (vector< float > data)
	Run the algorithm and store the results.
float	value (int index=0)
	Retrieve the results (from the index).
int	size ()
	Get the number of available values : computed from the size of the parent.
void	setFloat (string key, float value)
	Set a float parameter (available : base)
float	getFloat (string key)
	Get a int parameter (available : base)
Public Member Functions inherited from Filter
	Filter ()
	Default constructor : does nothing yet.
virtual	~Filter ()
	Destructor (inherited from FeatureExtractor)
FeatureExtractor *	bind (FeatureExtractor *extr)
	Binds the filter to the output of an extractor (or another filter). Returns the old one.
bool	extract (std::deque< uint16_t > data, int size=0)
	Extract data This method should not be reimplemented by the user. The given parameters are ignored : the data is drawn from the upstream extractor without taking care of the raw data.
virtual float	min ()
	Default min is the min of the parent.
virtual float	max ()
	Default max is the max of the parent.
Public Member Functions inherited from FeatureExtractor
	FeatureExtractor (int chunkSize=0)
	Constructor. Can set the typical chunk size.
virtual	~FeatureExtractor ()
	Virtual destructor : enables each extractor to delete arrays.
bool	extract (std::deque< uint16_t > data, int size, size_t start)
	Idem, but the buffer starts at index start instead (circular buffer)
virtual float	safeValue (int index=0)
	Retrieve the results, with the bounds respected (we apply a min / max)
virtual float	value (int index, float low, float high)
	Retrieve the results, with other bounds.
virtual void	setInt (string key, int value)
	Set a int parameter.
virtual int	getInt (string key)
	Get a int parameter.
virtual void	setString (string key, string value)
	Set a string parameter.
virtual string	getString (string key)
	Get a string parameter.
virtual void	clear ()
	Clear the memory of the extractor (so that the previously computed results don't infer to the next ones)

Protected Member Functions
void	parentChanged ()
	Update the sizes.

Additional Inherited Members
Protected Attributes inherited from Filter
FeatureExtractor *	mExtr
	The extractor from which the data is drawn.
