Sound
The Sound sink can be used to make data audible.
This can be both block mode data and streaming data.
It can play data through one of the installed sound cards.
If necessary, the data is resampled to fit the sound card's sample frequency.
One or two sources may be connected to each sound sink. If one source is connected, the data will be played in mono, otherwise in stereo. When playing stereo, the first source connected will be at the left and the second source at the right.
Properties
To control the behavior of the Sound sink, several properties and actions are available. These can be accessed through a popup menu which is shown when the sink is right clicked in the Object tree.
Play
The Play action plays the current content of the Sound sink.
Output
The Sound sink can play data through one of the installed sound outputs in the computer. The Output property selects which one is used. By default Wave mapper is used to output the data to.
Common properties and actions
Alias
You can change the displayed name of an object by giving it an Alias. This can be handy when you are dealing with a lot of objects and have problems keeping them apart. You can for example give channel one of your instrument the alias "Battery", when it is measuring a battery voltage. To give an object an alias, use the item Alias ... in its menu. To remove an alias and revert to the original name of the object, set the alias to an empty string.
Disconnect source(s)
To disconnect one or more sources from an I/O or Sink, use the Disconnect source(s) action. This will show a dialog that lists all connected sources. Individual sources can then be selected and disconnected from the object.
Disconnect all sources
To disconnect all sources from an I/O or Sink at once, use the Disconnect all sources action.
Clone
When a new object is to be created, similar to an already existing object, with the same properties, the Clone action can be used. This will create an identical copy of the original object, with the exact same properties. Source(s) and sink(s) of the new object are not yet connected.
Delete
The Delete action deletes a source, I/O or sink. All connections of the object will be disconnected and then the object will be removed from the object tree. The source property of the objects that used this object as source will be cleared. The sink property of the objects that used this object as sink will be cleared. An axis in a graph that was connected to this object will be also deleted.
Load
The Load action allows to load the settings and data for an object from a TPS or TPO file. This is detailed described on the page about Loading into selected objects.
Save as
The Save as action allows to save the settings and data of one or more objects to a TPO file. When multiple objects are selected, the connections between the objects are saved as well. This is detailed described on the page about Saving objects to a TPO file.
