audio.processing.tools.Normaliser

public class Normaliser
extends Unit

A Normalisation unit which allows the user to control the gain of the audio file's selection to the maximum level without clipping (digital distortion). The normalisation factor should be entered as a percentage from the maximum amplitude that the audio file should be normalised to.

Method Detail

process

public void process()
             throws java.lang.Exception

Description copied from class: Unit

The main unit algorithm. This method should be implemented with the appropriate algorihtm for the unit (if no algorithm is implemented deadlock occurs).

Specified by:

process in class Unit

Throws:

java.lang.Exception

init

public void init()

Called when the unit is created. Initialises the unit's properties and parameters.

Overrides:

init in class Unit

reset

public void reset()

Called when the unit is reset. Restores the unit's variables to values specified by the parameters.

Overrides:

reset in class Unit

dispose

public void dispose()

Called when the unit is disposed of.

Overrides:

dispose in class Unit

parameterUpdate

public void parameterUpdate(java.lang.String paramname,
                   java.lang.Object value)

Called a parameters is updated (e.g. by the GUI)

Overrides:

parameterUpdate in class Unit

getInputTypes

public java.lang.String[] getInputTypes()

Description copied from class: Unit

This method should return an array of the data types accepted by nodes not specified in getNodeInputTypes (e.g. triana.types.VectorType). If no package is specified then triana.types is assumed.

Specified by:

getInputTypes in class Unit

Returns:

an array of the input types for Normaliser

getOutputTypes

public java.lang.String[] getOutputTypes()

Description copied from class: Unit

This method should return an array of the data types output by nodes not specified in getNodeOutputTypes() (e.g. triana.types.VectorType). If no package is specified then triana.types is assumed.

Specified by:

getOutputTypes in class Unit

Returns:

an array of the output types for Normaliser
