Class SoundbankResource

java.lang.Object

javax.sound.midi.SoundbankResource

Direct Known Subclasses:

Instrument

public abstract class SoundbankResource
extends Object

A SoundbankResource represents any audio resource stored in a Soundbank. Common soundbank resources include:

• Instruments. An instrument may be specified in a variety of ways. However, all soundbanks have some mechanism for defining instruments. In doing so, they may reference other resources stored in the soundbank. Each instrument has a Patch which specifies the MIDI program and bank by which it may be referenced in MIDI messages. Instrument information may be stored in Instrument objects.
• Audio samples. A sample typically is a sampled audio waveform which contains a short sound recording whose duration is a fraction of a second, or at most a few seconds. These audio samples may be used by a Synthesizer to synthesize sound in response to MIDI commands, or extracted for use by an application. (The terminology reflects musicians' use of the word "sample" to refer collectively to a series of contiguous audio samples or frames, rather than to a single, instantaneous sample.) The data class for an audio sample will be an object that encapsulates the audio sample data itself and information about how to interpret it (the format of the audio data), such as an AudioInputStream.
• Embedded sequences. A sound bank may contain built-in song data stored in a data object such as a Sequence.

Synthesizers that use wavetable synthesis or related techniques play back the audio in a sample when synthesizing notes, often when emulating the real-world instrument that was originally recorded. However, there is not necessarily a one-to-one correspondence between the Instruments and samples in a Soundbank. A single Instrument can use multiple SoundbankResources (typically for notes of dissimilar pitch or brightness). Also, more than one Instrument can use the same sample.

Modifier and Type	Method	Description
protected Object	clone()	Answers a new instance of the same class as the receiver, whose slots have been filled in with the values in the slots of the receiver.
boolean	equals(Object o)	Compares the argument to the receiver, and answers true if they represent the same object using a class specific comparison.
protected void	finalize()	Deprecated, for removal: This API element is subject to removal in a future version. May cause performance issues, deadlocks and hangs.
final Class<? extends Object>	getClass()	Answers the unique instance of java.lang.Class which represents the class of the receiver.
int	hashCode()	Answers an integer hash code for the receiver.
final void	notify()	Causes one thread which is waiting on the receiver to be made ready to run.
final void	notifyAll()	Causes all threads which are waiting on the receiver to be made ready to run.
String	toString()	Answers a string containing a concise, human-readable description of the receiver.
final void	wait()	Causes the thread which sent this message to be made not ready to run pending some change in the receiver (as indicated by notify or notifyAll).
final void	wait(long time)	Causes the thread which sent this message to be made not ready to run either pending some change in the receiver (as indicated by notify or notifyAll) or the expiration of the timeout.
final void	wait(long time, int frac)	Causes the thread which sent this message to be made not ready to run either pending some change in the receiver (as indicated by notify or notifyAll) or the expiration of the timeout.

Constructor Details

SoundbankResource

protected SoundbankResource(Soundbank soundBank,
 String name,
 Class<?> dataClass)

Constructs a new SoundbankResource from the given sound bank and wavetable index. (Setting the SoundbankResource's name, sampled audio data, and instruments is a subclass responsibility.)

Parameters:

soundBank - the sound bank containing this SoundbankResource

name - the name of the sample

dataClass - the class used to represent the sample's data

See Also:

• getSoundbank()
• getName()
• getDataClass()
• getData()

Method Details

getSoundbank

public Soundbank getSoundbank()

Obtains the sound bank that contains this SoundbankResource.

Returns:

the sound bank in which this SoundbankResource is stored

getName

public String getName()

Obtains the name of the resource. This should generally be a string descriptive of the resource.

Returns:

the instrument's name

getDataClass

public Class<?> getDataClass()

Obtains the class used by this sample to represent its data. The object returned by getData will be of this class. If this SoundbankResource object does not support direct access to its data, returns null.

Returns:

the class used to represent the sample's data, or null if the data is not accessible

getData

public abstract Object getData()

Obtains the sampled audio that is stored in this SoundbankResource. The type of object returned depends on the implementation of the concrete class, and may be queried using getDataClass.

Returns:

an object containing the sampled audio data

• getDataClass()
