Chris@127 52 \section interesting Summary of interesting classes
Chris@127 53
Chris@127 54 - Data models: Model and subclasses, e.g. WaveFileModel
Chris@127 55
Chris@127 56 - Graphical layers: Layer and subclasses, displayed on View and its
Chris@127 57 subclass widgets.
Chris@127 58
Chris@127 59 - Main window class, document class, and file parser: MainWindow,
Chris@127 60 Document, SVFileReader
Chris@127 61
Chris@127 62 - Turning one model (e.g. audio) into another (e.g. more audio, or a
Chris@244 63 curve extracted from it): Transform, encapsulating the data that need
Chris@244 64 to be stored to be able to reproduce a given transformation;
Chris@244 65 TransformFactory, for discovering the available types of transform;
Chris@244 66 ModelTransformerFactory, ModelTransformer and subclasses, providing
Chris@244 67 the mechanisms for applying transforms to data models
Chris@127 68
Chris@127 69 - Creating the plugins used by transforms: RealTimePluginFactory,
Chris@129 70 FeatureExtractionPluginFactory. See also the API documentation for
Chris@129 71 Vamp feature extraction plugins at
Chris@129 72 http://www.vamp-plugins.org/code-doc/.
Chris@127 73
Chris@127 74 - File reading and writing code: AudioFileReader and subclasses,
Chris@127 75 WavFileWriter, DataFileReader, SVFileReader
Chris@127 76

Chris@127 78
Chris@127 79 - Widgets that show groups of editable properties: PropertyBox for
Chris@127 80 layer properties (contained in a PropertyStack), PluginParameterBox
Chris@127 81 for plugins (contained in a PluginParameterDialog)
Chris@127 82
Chris@127 83 - Audio playback: AudioCallbackPlaySource and subclasses,
Chris@127 84 AudioCallbackPlayTarget and subclasses, AudioGenerator
Chris@127 85
Chris@127 86 \section model Data sources: the Model hierarchy
Chris@127 87
Chris@127 88 A Model is something containing, or knowing how to obtain, data.
Chris@127 89
Chris@127 90 For example, WaveFileModel is a model that knows how to get data
Chris@127 91 from an audio file; SparseTimeValueModel is a model containing
Chris@127 92 editable "curve" data.
Chris@127 93
Chris@127 94 Models typically subclass one of a number of abstract subclasses of
Chris@127 95 Model. For example, WaveFileModel subclasses DenseTimeValueModel,
Chris@127 96 which describes an interface for models that have a value at each
Chris@127 97 time point for a given sampling resolution. (Note that
Chris@127 98 WaveFileModel does not actually read the files itself: it uses
Chris@127 99 AudioFileReader classes for that. It just makes data from the
Chris@127 100 files available in a Model.) SparseTimeValueModel uses the
Chris@127 101 SparseModel template class, which provides most of the
Chris@127 102 implementation for models that contain a series of points of some
Chris@127 103 sort -- also used by NoteModel, TextModel, and
Chris@127 104 SparseOneDimensionalModel.
Chris@127 105
Chris@127 106 Everything that goes on the screen originates from a model, via a
Chris@127 107 layer (see below). The models are contained in a Document object.
Chris@127 108 There is no containment hierarchy or ordering of models in the
Chris@127 109 document. One model is the main model, which defines the sample
Chris@127 110 rate for playback.
Chris@127 111
Chris@127 112 A model may also be marked as a "derived" model, which means it was
Chris@127 113 generated from another model using some transform (feature
Chris@127 114 extraction or effect plugin, etc) -- the idea being that they can
Chris@127 115 be re-generated using the same transform if a new source model is
Chris@127 116 loaded.
Chris@127 117
Chris@127 118 \section layer Things that can display data: the Layer hierarchy
Chris@127 119
Chris@127 120 A Layer is something that knows how to draw parts of a model onto a
Chris@127 121 timeline.
Chris@127 122
Chris@127 123 For example, WaveformLayer is a layer which draws waveforms, based
Chris@127 124 on WaveFileModel; TimeValueLayer draws curves, based on
Chris@127 125 SparseTimeValueModel; SpectrogramLayer draws spectrograms, based on
Chris@127 126 WaveFileModel (via FFTModel).
Chris@127 127
Chris@127 128 The most basic functions of a layer are: to draw itself onto a
Chris@127 129 Pane, against a timeline on the x axis; and to permit user
Chris@127 130 interaction. If you were thinking of adding the capability to
Chris@127 131 display a new sort of something, then you would want to add a new
Chris@127 132 layer type. (You may also need a new model type, depending on
Chris@127 133 whether any existing model can capture the data you need.)
Chris@127 134 Depending on the sort of data in question, there are various
Chris@127 135 existing layers that might be appropriate to start from -- for
Chris@127 136 example, a layer that displays images that the user has imported
Chris@127 137 and associated with particular times might have something in common
Chris@127 138 with the existing TextLayer which displays pieces of text that are
Chris@127 139 associated with particular times.
Chris@127 140
Chris@127 141 Although layers are visual objects, they are contained in the
Chris@127 142 Document in Sonic Visualiser rather than being managed together
Chris@127 143 with display widgets. The Sonic Visualiser file format has
Chris@127 144 separate data and layout sections, and the layers are defined in
Chris@127 145 the data section and then referred to in the layout section which
Chris@127 146 determines which layers may go on which panes (see Pane below).
Chris@127 147
Chris@127 148 Once a layer class is defined, some basic data about it needs to be
Chris@127 149 set up in the LayerFactory class, and then it will appear in the
Chris@127 150 menus and so on on the main window.
Chris@127 151
Chris@127 152 \section view Widgets that are used to show layers: The View hierarchy
Chris@127 153
Chris@127 154 A View is a widget that displays a stack of layers. The most
Chris@127 155 important subclass is Pane, the widget that is used to show most of
Chris@127 156 the data in the main window of Sonic Visualiser.
Chris@127 157
Chris@127 158 All a pane really does is contain a set of layers and get them to
Chris@127 159 render themselves (one on top of the other, with the topmost layer
Chris@127 160 being the one that is currently interacted with), cache the
Chris@127 161 results, negotiate user interaction with them, and so on. This is
Chris@127 162 generally fiddly, if not especially interesting. Panes are
Chris@127 163 strictly layout objects and are not stored in the Document class;
Chris@127 164 instead the MainWindow contains a PaneStack widget (the widget that
Chris@127 165 takes up most of Sonic Visualiser's main window) which contains a
Chris@127 166 set of panes stacked vertically.
Chris@127 167
Chris@127 168 Another View subclass is Overview, which is the widget that
Chris@127 169 contains that green waveform showing the entire file at the bottom
Chris@127 170 of the window.
