Quickfilter Technologies and Real Sound Lab Collaborate on Methodology to Control Audio Frequency Response

ALLEN, Texas & RIGA, Latvia--(BUSINESS WIRE)--Quickfilter Technologies, Inc., a fabless semiconductor company that develops mixed-signal ICs based on a programmable finite impulse response (FIR) engine for analog and digital signal processing, and Real Sound Lab, SIA, the company that has developed the world’s first Acoustic Power Equalizer, have collaborated to produce a methodology that enables audio engineers to control frequency response in audio applications. The resulting collaborative methodology can be applied to a wide range of applications ranging from professional sound reinforcement to different products in the consumer audio electronics market segment.

In many of today’s consumer audio applications such as flat-panel TVs, docking stations and radios, sound performance is compromised through cost and industry design constraints. Product size and mechanical cabinet needs can have a detrimental effect on audio quality. Audio engineers try to compensate for such problems but the cost involved often limits the results.

The collaborative methodology combines the Real Sound Lab CONEQ™ (CONvolution EQualizer), a software-based technology for automated and detailed equalization of acoustic systems, with the Quickfilter QF1D512 Simple and versatile FIR engine (SavFIRe) programmable digital filter. The CONEQ technology generates a speaker transfer function representing the acoustic power of the speaker along with the inverse transfer function which can be imported into the QF1D512 IC. The resulting FIR takes minutes to design and implement.

In addition to controlling the frequency response of the audio system, the collaborative technology can also flatten the final response to make the speaker a transparent transducer. Moreover, the collaborative technology also allows the audio engineer to select specific areas of the frequency spectrum to augment, such as providing bass boost capability.

Real Sound Lab is in the process of establishing a similar link on its website.

“The combination of the Real Sound Lab CONEQ technology with the Quickfilter Technologies digital filtering ICs provides our customers with an exceptionally low-power, low-cost solution for solving speaker equalization problems,” said Tony Valentino, Chief Operating Officer for Quickfilter Technologies, Inc. “Together, we improve audio quality while reducing the time-to-market for consumer audio systems.”

“The collaboration with Quickfilter Technologies provides the means of implementing our technology in silicon at the lowest possible cost, enhancing the value of the CONEQ,” said Yoshi Asahi, President of the Real Sound Lab USA, a US subsidiary of Real Sound Lab, SIA. “We strongly believe that this solution will provide our customers in various consumer audio markets with a cost-effective option for capturing of all benefits of using CONEQ technology.”

About Quickfilter Technologies

From Concept to Product in Minutes, not Days

Quickfilter Technologies, Inc utilizes patent pending techniques for implementing a programmable IC that allows an engineer to design a custom circuit for signal processing without the cost and complexity of programming a DSP. Quickfilter’s products are ideally suited for consumer audio, medical equipment, industrial controls, homeland security, and automotive applications.

The Quickfilter solution comprises over a dozen individual component functions, both analog and digital, into a single integrated circuit (IC) that is programmable using Quickfilter software. This enables customer to rapidly complete a design at significantly lower cost and higher performance. In addition, the IC can be reprogrammed in circuit during design, at the time of shipment or in the field.

Quickfilter Technologies Inc. is a private equity funded fabless semiconductor company founded in 2003 by Bob Silco. The company, which has its headquarters in Allen, TX, is developing a family of programmable mixed-signal integrated circuits that convert noisy analog signals into clean, usable digital signals.
