Interface Soundbank
public interface Soundbank
A Soundbank contains a set of Instruments
that can be loaded into a Synthesizer .
Note that a Java Sound Soundbank is different from a MIDI bank.
MIDI permits up to 16383 banks, each containing up to 128 instruments
(also sometimes called programs, patches, or timbres).
However, a Soundbank can contain 16383 times 128 instruments,
because the instruments within a Soundbank are indexed by both
a MIDI program number and a MIDI bank number (via a Patch
object). Thus, a Soundbank can be thought of as a collection
of MIDI banks.
Soundbank includes methods that return String
objects containing the sound bank's name, manufacturer, version number, and
description. The precise content and format of these strings is left
to the implementor.
Different synthesizers use a variety of synthesis techniques. A common
one is wavetable synthesis, in which a segment of recorded sound is
played back, often with looping and pitch change. The Downloadable Sound
(DLS) format uses segments of recorded sound, as does the Headspace Engine.
Soundbanks and Instruments that are based on
wavetable synthesis (or other uses of stored sound recordings) should
typically implement the getResources()
method to provide access to these recorded segments. This is optional,
however; the method can return an zero-length array if the synthesis technique
doesn't use sampled sound (FM synthesis and physical modeling are examples
of such techniques), or if it does but the implementor chooses not to make the
samples accessible.

SoundbankResource
getName
String getName()
- Obtains the name of the sound bank.
- Returns:
- a
String naming the sound bank
getVersion
String getVersion()
- Obtains the version string for the sound bank.
- Returns:
- a
String that indicates the sound bank's version
getVendor
String getVendor()
- Obtains a
string naming the company that provides the
sound bank
- Returns:
- the vendor string
getDescription
String getDescription()
- Obtains a textual description of the sound bank, suitable for display.
- Returns:
- a
String that describes the sound bank
getResources
SoundbankResource[] getResources()
- Extracts a list of non-Instrument resources contained in the sound bank.
- Returns:
- an array of resources, exclusing instruments. If the sound bank contains
no resources (other than instruments), returns an array of length 0.
getInstruments
Instrument[] getInstruments()
- Obtains a list of instruments contained in this sound bank.
- Returns:
- an array of the
Instruments in this
SoundBank
If the sound bank contains no instruments, returns an array of length 0. - See Also:
Synthesizer.getLoadedInstruments() ,
getInstrument(Patch)
getInstrument
Instrument getInstrument(Patch patch)
- Obtains an
Instrument from the given Patch .
- Parameters:
patch - a Patch object specifying the bank index
and program change number
- Returns:
- the requested instrument, or
null if the
sound bank doesn't contain that instrument - See Also:
