|
Chris@127
|
58
|
Chris@127
|
59 - Data models: Model and subclasses, e.g. WaveFileModel
|
Chris@127
|
60
|
Chris@127
|
61 - Graphical layers: Layer and subclasses, displayed on View and its
|
Chris@127
|
62 subclass widgets.
|
Chris@127
|
63
|
Chris@127
|
64 - Main window class, document class, and file parser: MainWindow,
|
Chris@127
|
65 Document, SVFileReader
|
Chris@127
|
66
|
Chris@127
|
67 - Turning one model (e.g. audio) into another (e.g. more audio, or a
|
Chris@244
|
68 curve extracted from it): Transform, encapsulating the data that need
|
Chris@244
|
69 to be stored to be able to reproduce a given transformation;
|
Chris@244
|
70 TransformFactory, for discovering the available types of transform;
|
Chris@244
|
71 ModelTransformerFactory, ModelTransformer and subclasses, providing
|
Chris@244
|
72 the mechanisms for applying transforms to data models
|
Chris@127
|
73
|
Chris@127
|
74 - Creating the plugins used by transforms: RealTimePluginFactory,
|
Chris@129
|
75 FeatureExtractionPluginFactory. See also the API documentation for
|
Chris@129
|
76 Vamp feature extraction plugins at
|
Chris@129
|
77 http://www.vamp-plugins.org/code-doc/.
|
Chris@127
|
78
|
Chris@127
|
79 - File reading and writing code: AudioFileReader and subclasses,

|
Chris@127
|
81
|
Chris@127
|
82 - FFT calculation and cacheing: FFTModel, FFTDataServer
|
Chris@127
|
83
|
Chris@127
|
84 - Widgets that show groups of editable properties: PropertyBox for
|
Chris@127
|
85 layer properties (contained in a PropertyStack), PluginParameterBox
|
Chris@127
|
86 for plugins (contained in a PluginParameterDialog)
|
Chris@127
|
87
|
Chris@127
|
88 - Audio playback: AudioCallbackPlaySource and subclasses,
|
Chris@127
|
89 AudioCallbackPlayTarget and subclasses, AudioGenerator

|
Chris@127
|
91 \section model Data sources: the Model hierarchy
|
Chris@127
|
92
|
Chris@127
|
93 A Model is something containing, or knowing how to obtain, data.
|
Chris@127
|
94
|
Chris@127
|
95 For example, WaveFileModel is a model that knows how to get data
|
Chris@127
|
96 from an audio file; SparseTimeValueModel is a model containing
|
Chris@127
|
97 editable "curve" data.
|
Chris@127
|
98
|
Chris@127
|
99 Models typically subclass one of a number of abstract subclasses of
|
Chris@127
|
100 Model. For example, WaveFileModel subclasses DenseTimeValueModel,
|
Chris@127
|
101 which describes an interface for models that have a value at each
|
Chris@127
|
102 time point for a given sampling resolution. (Note that
|
Chris@127
|
103 WaveFileModel does not actually read the files itself: it uses
|
Chris@127
|
104 AudioFileReader classes for that. It just makes data from the
|
Chris@127
|
105 files available in a Model.) SparseTimeValueModel uses the
|
Chris@127
|
106 SparseModel template class, which provides most of the
|
Chris@127
|
107 implementation for models that contain a series of points of some
|
Chris@127
|
108 sort -- also used by NoteModel, TextModel, and
|
Chris@127
|
109 SparseOneDimensionalModel.
|
Chris@127
|
110
|
Chris@127
|
111 Everything that goes on the screen originates from a model, via a
|
Chris@127
|
112 layer (see below). The models are contained in a Document object.
|
Chris@127
|
113 There is no containment hierarchy or ordering of models in the
|
Chris@127
|
114 document. One model is the main model, which defines the sample
|
Chris@127
|
115 rate for playback.
|
Chris@127
|
116
|
Chris@127
|
117 A model may also be marked as a "derived" model, which means it was
|
Chris@127
|
118 generated from another model using some transform (feature
|
Chris@127
|
119 extraction or effect plugin, etc) -- the idea being that they can
|
Chris@127
|
120 be re-generated using the same transform if a new source model is
|
Chris@127
|
121 loaded.
|
Chris@127
|
122
|
Chris@127
|
123 \section layer Things that can display data: the Layer hierarchy
|
Chris@127
|
124
|
Chris@127
|
125 A Layer is something that knows how to draw parts of a model onto a
|
Chris@127
|
126 timeline.
|
Chris@127
|
127
|
Chris@127
|
128 For example, WaveformLayer is a layer which draws waveforms, based
|
Chris@127
|
129 on WaveFileModel; TimeValueLayer draws curves, based on
|
Chris@127
|
130 SparseTimeValueModel; SpectrogramLayer draws spectrograms, based on
|
Chris@127
|
131 WaveFileModel (via FFTModel).
|
Chris@127
|
132
|
Chris@127
|
133 The most basic functions of a layer are: to draw itself onto a
|
Chris@127
|
134 Pane, against a timeline on the x axis; and to permit user
|
Chris@127
|
135 interaction. If you were thinking of adding the capability to
|
Chris@127
|
136 display a new sort of something, then you would want to add a new
|
Chris@127
|
137 layer type. (You may also need a new model type, depending on
|
Chris@127
|
138 whether any existing model can capture the data you need.)
|
Chris@127
|
139 Depending on the sort of data in question, there are various
|
Chris@127
|
140 existing layers that might be appropriate to start from -- for
|
Chris@127
|
141 example, a layer that displays images that the user has imported
|
Chris@127
|
142 and associated with particular times might have something in common
|
Chris@127
|
143 with the existing TextLayer which displays pieces of text that are
|
Chris@127
|
144 associated with particular times.
|
Chris@127
|
145
|
Chris@127
|
146 Although layers are visual objects, they are contained in the
|
Chris@127
|
147 Document in Sonic Visualiser rather than being managed together
|
Chris@127
|
148 with display widgets. The Sonic Visualiser file format has
|
Chris@127
|
149 separate data and layout sections, and the layers are defined in
|
Chris@127
|
150 the data section and then referred to in the layout section which
|
Chris@127
|
151 determines which layers may go on which panes (see Pane below).
|
Chris@127
|
152
|
Chris@127
|
153 Once a layer class is defined, some basic data about it needs to be
|
Chris@127
|
154 set up in the LayerFactory class, and then it will appear in the
|
Chris@127
|
155 menus and so on on the main window.
|
Chris@127
|
156
|
Chris@127
|
157 \section view Widgets that are used to show layers: The View hierarchy
|
Chris@127
|
158
|
Chris@127
|
159 A View is a widget that displays a stack of layers. The most
|
Chris@127
|
160 important subclass is Pane, the widget that is used to show most of
|
Chris@127
|
161 the data in the main window of Sonic Visualiser.
|
Chris@127
|
162
|
Chris@127
|
163 All a pane really does is contain a set of layers and get them to
|
Chris@127
|
164 render themselves (one on top of the other, with the topmost layer
|
Chris@127
|
165 being the one that is currently interacted with), cache the
|
Chris@127
|
166 results, negotiate user interaction with them, and so on. This is
|
Chris@127
|
167 generally fiddly, if not especially interesting. Panes are
|
Chris@127
|
168 strictly layout objects and are not stored in the Document class;
|
Chris@127
|
169 instead the MainWindow contains a PaneStack widget (the widget that
|
Chris@127
|
170 takes up most of Sonic Visualiser's main window) which contains a
|
Chris@127
|
171 set of panes stacked vertically.
|
Chris@127
|
172
|
Chris@127
|
173 Another View subclass is Overview, which is the widget that
|
Chris@127
|
174 contains that green waveform showing the entire file at the bottom
|
Chris@127
|
175 of the window.
