Outline Awarded European Patent for Warped Finite Impulse (WFIR) Technology

	WFIR filters are the most distinctive feature aboard Outline Newton, the company says.

After being awarded an Italian patent in 2022, Outline's technology for its Warped Finite Impulse (WFIR) filter has now been granted a European patent, EP3763134, by the European Patent Office.

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 underlines the significance of the European grant now awarded to Outline.

WFIR filters are the most distinctive feature aboard Outline Newton, the FPGA-based audio system control and networking digital processor, which has been employed in many complex applications before huge audiences at entertainment and civil-religious gatherings worldwide, the company says.

In a statement, the company says, "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 the case of increasingly high sampling frequencies.

"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 equalization.

"Add to this the further benefit of a 10X-res factor at mid-low frequencies, where it matters most in live sound -- all while being impervious to the latency issues that traditionally affect FIR filters, too, and you realize what tangible benefits Outline Newton empowers its user base with."

The Brescia, Italy-based Outline introduced Newton in 2017.
