Multi-layered graphical user interface for constructing block diagram models of flow duct networks with multiple sources and outlets; block diagrams can be linked to a drawing or a sketch of the system.

Open end radiation into fractional free-fields and diffuse fields.

Signal analyzer for driving sources, audio play, and post-processing of results or measured signals.

User-friendly input datasheets with formula writing, syntax and compatibility checking capabilities.

Parametric and doe calculations with arbitrary number of parameters, direct, stochastic, and inverse optimization capabilities; results are plotted on-line and can be stored in a file.

Element database contains passive two-ports and multi-ports with variable and fixed number of ports in 1-D and 3-D, and active one-port and two-port elements. Measured or FEM based elements can be imported; users can create (without any programming) new passive elements in 1-D and 3-D and new active one-ports.

Measurement of one-port source characteristics and two-port transfer matrices by state-of-the-art methods.

Frequency analysis and order analysis capabilities under ambient gradients and fluid options (gas, liquid, burnt product, refrigerant, etc.); mean pressure losses in elements are calculated along with acoustic calculations.

Extensive on-line help, tutorials and compact installation.
