Forensic Audio Analysis

Voice Clarity is Job 1

Vocal intelligibility can make or break a legal or business case. Advanced spectral analysis and the latest algorithmic noise reduction, combined with years of sound restoration experience, achieve clarity that makes most clients simply say "wow."

Critical Noise

Noise focus can identify any non-vocal sounds you deem to be important in a recording. These include writing, paper rustling, background location identifiers, potential edits, pauses, and equipment malfunction, and any other sounds of interest.

Metadata Deep-dive

We examine your audio with a critical metadata analysis. You receive a report that includes telling details of your recording such as date and time, length, demographics, recorder make/model, serial number, device settings, and user data such as investigator or case number.

Unlimited Revisions

Audio is mission-critical to your work so we guarantee 100% no-compromise satisfaction. We are always happy to oblige when a client wants to try to achieve more clarity around specific audio events.

John Giuca's case

John Giuca

"Prosecuting Attorney Anna-Sigga Nicolazzi claimed, 'No notes were taken' therefore there was nothing to turn over to the defense. Mark's audio forensics mastery enhanced the sound recording of the deposition which clearly exposed scribbling sounds, pen drops, and page turning! The PA has since been accused of hiding favorable evidence from the defendant and false representations and nondisclosure of evidence. My son and I are so grateful for Mark's work!" -Doreen Giuliano

Stephanie Ewens

Director & Photojournalist

Working with Mark is awesome. He has a deep knowledge of sound and a ton of experience. He's an excellent listener and delivered exactly what I asked for. I've worked with him on multiple projects including a commercial, on which he went above and beyond to make sure I got what I needed and all before deadline. I can't recommend Mark enough!
