After having been awarded an Italian patent in 2022, Outline’s technology for Warped Finite Impulse (WFIR) filter has now been granted by the European Patent Organisation.
Developed in-house by the company’s engineering team, the design of Outline’s Warped Finite Impulse Response (WFIR) filters is now protected by an international patent – as European Patent EP3763134 was recently granted to Outline by the European Patent Office.
WFIR filters are a distinctive feature of Outline’s Newton, employed in complex applications before huge audiences worldwide to drive a palette of loudspeakers from different manufacturers as genuinely a brand-agnostic processor.
The designation of ‘warped finite impulse response’ technology for sound processing applications has been the subject of several patents across the professional audio and audiology sectors – a broader context that further underlines the significance of the European grant now awarded to Outline.
‘Substantial improvements over traditional FIR filters are intrinsic to WFIR filters, which – thanks to their semi-logarithmic scale operation, in line with the very nature of human hearing – maintain maximum filtering resolution over the entire audio range – even in case of increasingly high sampling frequencies’, the company says.
‘Taming the high impact on computing power associated with traditional FIR filters, which Newton nonetheless more-than-adequately provides for, WFIR technology also allows the use of raised cosine filters for a superior level of accuracy in equalisation. Add to this the further benefit of a 10X-res factor at mid-low frequencies, where it matters most in live sound – all the while being impervious to the latency issues that traditionally affect FIR filters, too, and you realise what tangible benefits Outline Newton empowers its users-base with.’
While the technical performance and behaviour of WFIR filters can be demonstrated with T&M platforms (for instance, Audio Precision toolsets), users in the field claim the audible advantages are evident in real-world applications.
