31 * A {@code SoundbankResource} represents any audio resource stored in a
32 * {@link Soundbank}. Common soundbank resources include:
33 * <ul>
34 * <li>Instruments. An instrument may be specified in a variety of ways.
35 * However, all soundbanks have some mechanism for defining instruments. In
36 * doing so, they may reference other resources stored in the soundbank. Each
37 * instrument has a {@code Patch} which specifies the MIDI program and bank by
38 * which it may be referenced in MIDI messages. Instrument information may be
39 * stored in {@link Instrument} objects.</li>
40 * <li>Audio samples. A sample typically is a sampled audio waveform which
41 * contains a short sound recording whose duration is a fraction of a second, or
42 * at most a few seconds. These audio samples may be used by a
43 * {@link Synthesizer} to synthesize sound in response to MIDI commands, or
44 * extracted for use by an application. (The terminology reflects musicians' use
45 * of the word "sample" to refer collectively to a series of contiguous audio
46 * samples or frames, rather than to a single, instantaneous sample.) The data
47 * class for an audio sample will be an object that encapsulates the audio
48 * sample data itself and information about how to interpret it (the format of
49 * the audio data), such as an {@link AudioInputStream}.</li>
50 * <li>Embedded sequences. A sound bank may contain built-in song data stored in
51 * a data object such as a {@link Sequence}.</li>
52 * </ul>
53 * Synthesizers that use wavetable synthesis or related techniques play back the
54 * audio in a sample when synthesizing notes, often when emulating the
55 * real-world instrument that was originally recorded. However, there is not
56 * necessarily a one-to-one correspondence between the {@code Instruments} and
57 * samples in a {@code Soundbank}. A single {@code Instrument} can use multiple
58 * SoundbankResources (typically for notes of dissimilar pitch or brightness).
59 * Also, more than one {@code Instrument} can use the same sample.
