All CODA systems are phase-linear and will work together without compromise. This eliminates the need to apply destructive processing when combining different elements in complex systems (see fig. below).
- Ease of use
- Compatibility between products
- Fewer potential reliability issues in complex systems
- Better fidelity and more faithful imaging
Attaining phase linearity is no simple task. A heavier processing load with a longer time window (typically 45–60 ms) is normally required to achieve a linear phase response that extends to the lower frequency range.
The secret to CODA’s DS-FIR is multisampling with a combination of filters, each set to a length that is precisely adapted to the virtual and acoustical crossover points. CODA’s proprietary combination of filters results in a loudspeaker system with incredible fidelity throughout its operating range and a reduced latency of 11 ms that is acceptable in PA practice.
While many of today’s professional loudspeakers feature a linear frequency response — exhibiting a frequency response that remains the same regardless of output level — very few feature a linear phase response, and are often not phase-compatible with other loudspeakers in their own product lines. Such arrangements require additional, time-intensive system tuning. CODA systems offer linearity not just for each individual element, but for the entire system, right out of the box.
