Hank Waring and FDS Labs
Forensic Audio and Video Laboratories



FDS Labs has “cleaned-up” recorded audio evidence for regional, State and Federal court systems, law enforcement, and other government agencies for over 50 years. We are currently privileged to reside on a panel of experts for the Los Angeles County Superior Court, identifying our company to more than 500 judicial officers who preside over cases in Los Angeles, Orange and San Bernardino Counties. FDS Labs was honored to be among the first organizations appointed to this panel in 1991.

Our forensic clients include courts of law in Los Angeles, Orange, Riverside, Santa Barbara and San Bernardino Counties, the Los Angeles County Sheriff’s Department, Los Angeles County Council, City of Los Angeles and other municipalities, district attorneys’ offices, alternate and public defenders, private attorneys and investigators, as well as other U.S. and foreign government and private agencies.

In addition to our forensic services, FDS Labs offers MCLE training classes to groups of legal professionals seeking a better understanding of the technologies involved.

FDS Labs originated in 1964 as DCT Recorders in Hollywood, California. At that time, our services included the restoration, enhancement and clarification of recorded audio, and noise removal from aging tape recordings, vinyl phonograph records, and vintage or damaged film soundtracks.

We also provided state-of-the-art audio mastering services for the record industry, working with virtually all audio formats, including phonograph records, analog reel to reel, and audio cassettes.

In 1965, we expanded our services to provide forensic audio processing and analysis for the courts and law enforcement agencies.
