GAO Research Inc. (GAO) is a recognized international leading R & D organization in various technology fields and a leading provider of engineering software, and technologies to world-class companies.

With a modest beginning in 1992, providing consulting services in DSP algorithms and audio software. GAO strategically repositioned in 1995 to target the engineering design market.

Today, the company provides the most comprehensive and unique suite of modem, fax, telephony, speech software, VoIP, fax relay, and fax/modem/voice relay software, RFID, environmental, chemical, and mechanical designs.

Solutions & Products

Interest in software implementations of communication functions has increased over the years because they offer better cost/performance ratios than fixed function chip sets, in addition to their unmatched flexibility in functional and technological upgrades.

GAO provides the most comprehensive and unique suite of modem, fax, telephony, speech, Voice over IP (VoIP), fax relay, fax/modem/voice relay and fax/modem/voice over IP/wireless software on a wide range of DSPs and microprocessors. GAO’s products have been widely reported by numerous most influential international publications in the industry.

GAO software is available in modules or packages. A module implements a function for a particular standard such as V.34 color fax, V.92 modem, G.723.1 vocoder, etc. A package contains a group of modules where each one performs a single function and they collectively perform a complete application. For example, GAO V.92 modem package integrates the V.92 function and all its fallbacks as well as protocols and control functions. The customer may license a module, one of GAO’s existing packages, or a customized package. GAO’s software fully complies with all ITU and other applicable standards for interoperability purposes, and is exhaustively tested before delivery to its customers. GAO performs fine-tuning on its code to meet any customer’s specific requirements such MIPS/MHz and Memory utilization.
