In 1975 Greg Ogonowski founded Gregg Laboratories, a broadcast audio signal processing company, and has had considerable experience designing commercial broadcast audio processing systems which have been used by many high profile broadcasters.  He has extensively researched the characteristics of consumer radio receivers, and has co-authored a technical paper with Robert Orban, presented before the Society of Automotive Engineers and National Association of Broadcasters regarding the standardization of pre-emphasis in AM broadcast.  This was the onset of the AM-NRSC.

He has also authored many other technical papers on various topics relating to the audio and broadcast industry.

In 1984 he founded Modulation Index, a broadcast engineering consultancy, and has done studies on broadcast modulation measurement instrumentation and FM modulators, including STL's and exciters.  As a result of these studies, he has developed modifications for popular monitors, STL'S, and exciters to improve their dynamic transient accuracy and competitiveness.  A technical paper was presented before the National Association of Broadcasters regarding these findings.  He has developed audio signal processing algorithms which later became included in all of the current generation Orban Optimod line of audio processors.

As technical director for KTNQ/KLVE, Heftel Broadcasting, Los Angeles, from 1985 to 1991, he relocated studio facilities and constructed a new efficient alternative use AM transmission facility.  Later becoming technical director for KBIG/KLAC, Los Angeles, from 1998 to 2000, he installed a new computer network and digital audio delivery system throughout the business and technical facility.  KBIG/KLAC was one of the first radio stations to stream audio on the Internet with high fidelity sound, all from internal encoders and servers.

After Ogonowski joined Orban in 2000 as VP Product Development, he led the team that created Optimod-PC, a digital audio signal processed PCI sound card for any digital audio or streaming application. He currently oversees the engineering department, where audio encoders, editors, and signal processors currently under development will enable Orban to continue in its tradition of high quality, high performance broadcast technology.

Destined to change the way streaming audio is perceived and consumed, he architechted the first high quality file and streaming audio encoder using standards-based MPEG-4 AAC/HE-AAC, Orban Opticodec-PC.
