58 -- SEQUENTIAL UNKNOWN REFERENCE FINDER SOL RFP-7040 DUE 092096 POC Charles A. Weschler, Contract Specialist, (202) 324-2263. The Federal Bureau of Investigation (FBI) intends to negotiate with the Digital Audio Company (DAC) on a sole source basis for the design and fabrication of a Sequential Unknown Reference Finder (SURF) to interface with the FBI's existing audio equipment. On the basis of two-channel adaptive noise canceling algorithm, the Reference Signal is used to extract desired voice speeches masked by the Reference Signal (here noise). SURF is to find the source of masking noise when the source changes. SURF and the FBI's audio equipment are to be integrated to operate on a real-time mode for masking noise cancellations to extract the desired voice speech. The SURF operates as a tracking device for changing interference sources, while the audio equipment is a DAC multichannel adaptive noise canceling processor. All interested vendors should submit their proposals to the address listed above by no later than 4:00pm local time on 9/20/96. Additionally, offerors shall provide with their proposals a complete description of their qualifications which demonstrate to the FBI's satisfaction that the offeror possess the capabilities to meet the FBI's needs.
