Projection prediction software enables engineers to model system behaviour and rigging requirements with speed and accuracy. An unprecedented and industry leading feature is its ability to model low frequency behaviour correctly. This is achieved with a wave-based low-frequency calculation model (patents-pending) – unique to Funktion-One – which accurately predicts bass array behaviour by taking into account the effect on directivity of the speaker enclosures’ physical size and presence.

Projection allows users to quickly build complex venues in 2D, streamlining the design process with an intuitive interface. Users can seamlessly add arrays, individual loudspeakers and microphones, optimising both mechanical and electronic array settings. The software’s advanced 3D view enables SPL calculations, providing a comprehensive visualisation of the design and allowing for precise adjustments.

Projection features two powerful 3D SPL calculation algorithms, including a new fast wave-based low-frequency model. This breakthrough technology fully predicts linear wave behaviour, including reflections, diffractions and occlusions, ensuring accurate performance simulations. The physical geometry of the loudspeakers is included in the calculation, a feature previously limited to expensive, specialised R&D software requiring powerful hardware. For frequencies above 160Hz, the real-time point source model delivers immediate and accurate insights into system behaviour. 

Projection’s wave-based low-frequency model represents a major breakthrough in bass array simulation. Traditional industry-standard modelling relies on the complex directivity point source model, which assumes loudspeakers are infinitely small relative to their emitted wavelengths. While effective for small bass speakers or stacks, this method loses accuracy as arrays increase in size.

Funktion-One initially implemented a point source model but identified key limitations: accuracy diminishes with larger bass arrays and users are constrained to predefined configurations. In response, the loudspeaker manufacturer embarked on an extensive research project, leading to the development of the fast wave-based model.

The wave-based model offers significant advantages: greater flexibility in bass array design, accurate results across configurations and freedom for users to experiment beyond traditional measured array setups. Novel cardioid arrays can be designed and tested with confidence, as the model correctly calculates acoustic path lengths and their impact on phase interactions.

Additional benefits include automatic inclusion of subtleties such as periodic gaps in broadside arrays and scattering effects from adjacent bass loudspeakers. End-fired arrays can be accurately simulated, as the acoustic effects of the physical presence of one cabinet in front of another is automatically included in the calculation.
