Forensic Audio

Zone Recording specializes in forensic audio restoration for law enforcement agencies and attorneys.

Vital evidence for criminal trials is often found in muffled, noisy, incoherent audio recordings.  At Zone Recording, our audio engineers and forensic audio specialist can successfully restore or “clean up” audio recordings that can then be used as evidence in a court of law.

Our software can reduce background noise and make voices intelligible. We work with micro-cassette, cassette, reel to reel, digital audio and video tape.

Our studio observes the evidence chain of custody. We also provide transferring and copying services in all formats.
