audio.input.LoadMP3

public class LoadMP3
extends Unit

A class for a Unit which allows the user to load a sound file into Triana. This unit allows the user to split the audio into a stream of contiguous chunks, and output, or as the whole sound file in its entirety. Created by Dr. Ian Taylor.

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

createAudioInputStream

public static void createAudioInputStream(java.io.File file)

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

getNodeInputTypes

public java.lang.String[][] getNodeInputTypes()

Description copied from class: Unit

This method should return an array of the data types accepted by specific nodes, with the node index providing the index for the array. For nodes not covered by the array, the types specified by getInputTypes() are assumed.

Overrides:

getNodeInputTypes in class Unit

Returns:

an array of the types accepted by each input node. For node indexes not covered the types specified by getInputTypes() are assumed.

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 accepted by nodes not covered by getNodeInputTypes().

getNodeOutputTypes

public java.lang.String[][] getNodeOutputTypes()

Description copied from class: Unit

This method should return an array of the data types output by specific nodes, with the node index providing the index for the array. For nodes not covered by the array, the types specified by getOutputTypes() are assumed.

Overrides:

getNodeOutputTypes in class Unit

Returns:

an array of the types output by each output node. For node indexes not covered the types specified by getOutputTypes() are assumed.

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 input types output by nodes not covered by getNodeOutputTypes().
