Chris@127 57 \section interesting Summary of interesting classes
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 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 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 90
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.
