Audia-Manual-LTR
Multiple component objects may be merged together using the Custom Blocks menu. Custom
Blocks can then be copied to the Processing Library as mentioned above. Custom Blocks can
simplify the design process by integrating frequently used component combinations, and can
provide password protection for intellectual property such as unique processing and component
settings.
Right-clicking over the Processing Library will also allow new category files (.APL) to be created,
for quick access to specialized or often-used components. Existing category files (.APL) can be
closed, to customize the Processing Library. All available category files (.APL) can be viewed and
opened from the Processing Library Menu and from the Open dialog box. When Processing
Library changes are made, the affected category files (.APL) are automatically saved (under
Shared Documents).
Object and Layout Text
The size and appearance of both text and objects can be customized. Special Text Objects can
be placed into the Layout using the Text cursor on the
Object Toolbar . When selected,
Component & Text Objects display handles which can be dragged for re-sizing. Right-clicking
over an object provides a pop-up menu which includes the Edit Text option. Edit Text can also be
accessed for a selected object by simply pressing the Enter key. Text (and object) appearance
can be customized using the associated tools on the
Format Toolbar . Also, Line Objects (wires)
can have identifying text added (see Line Property Sheet ).
System Compiling Considerations
Once a system design is created (components placed & connected), the system can be
compiled by selecting
Compile from either the File Menu or the Standard Toolbar . Compile
provides system design analysis and calculates DSP processing requirements. Compile also
makes initial determinations of quantity/type of Audia®
devices needed, CobraNet® channel
assignments, allocation of DSP resources, and I/O channel number assignments . In addition,
Compile will provide an indication of system design errors.
Although Compile is an automatic process, certain settings can be pre-determined to help guide
this process. DSP blocks (components) can be
Allocated To Unit , which assigns them to a
particular Audia device. This can be useful either to dedicate particular audio functions to
specific physical locations, or to reduce the number of CobraNet channels being transmitted
between Audia devices (reduces propagation delay).
Propagation Delay (also known as Latency) is an inherent time delay of the audio signals, which
increases with the amount of DSP processing and CobraNet routing applied. Each CobraNet
'hop' (one-way transmission) produces 5.33mS delay (see
CN Latency ). Therefore, system
outputs can have different amounts of propagation delay. Compile determines worst-case
propagation delay for a system, and applies Delay Equalization to synchronize all audio outputs.
In applications where audio output synchronization is not important (audibly isolated areas),
then Delay Equalization may be disabled on individual Input Output components (DSP blocks)
or system wide. See
Object Property Sheet and Compile Options .
