Outline’s WFIR technology receives patent

Italy - Developed entirely in-house by their engineering team, the design of Outline’s Warped Finite Impulse Response (WFIR) filters is now protected by a domestic patent and will soon enjoy the same status internationally. Italian Patent N. 102018000003311 has been awarded to this innovation. WFIR filters are one of the key features found in Outline’s Newton FPGA processor.
“WFIR filters offer fundamental technical improvements over traditional FIR filters in that they operate on a semi-logarithmic scale, similar to the nature of human hearing. This means that they are able to maintain high filtering resolution over the entire audio range, even in the case of increasingly high sampling frequencies,” says Outline.
“WFIR technology also allows the use of raised cosine filters which provide a greatly enhanced level of accuracy in equalization. They do require up to three times the computing power required for traditional FIR filters (not a problem with Newton’s onboard processing power), but in turn they provide up to 10 times the resolution on mid-low frequencies. They are also not subject to the latency artifacts suffered by FIR filters.”
