Why Attorneys and Insurers Rely on Stutchman Forensic

We help you understand the digital evidence so you can make informed settlement decisions or proceed to trial with confidence.

What We Do

Forensic Audio Analysis Services

Every examination follows documented forensic methodology, preserving the integrity of the original recording and chain of custody from intake to courtroom. A noisy, muffled, or unclear recording is only part of the picture. Our digital audio forensics process addresses what a recording can reliably establish, not just how clean it sounds after processing.

Audio Forensics - Forensic audio enhancement Services - Audio Expert
  • Audio Enhancement, Clarification, and Restoration: Noise reduction and speech clarification for 911 calls, jail calls, body-worn camera audio, wiretaps, and consensual recordings.
  • Audio Authentication Analysis: Forensic sound examination of recording artifacts, background noise consistency, timestamps, and metadata to assess whether a recording is consistent with an original and free of tampering.
  • Timing and Synchronization: Temporal alignment of audio with video or other time-based evidence, speech timing and pacing analysis, and timeline reconstruction across multiple sources.
  • Demonstrative Evidence: Clear exhibits, synchronized timelines, and annotated audio prepared for deposition and trial.
  • Transcription & Subtitles: We have a preferred partner we work with to provide legal transcription. Then we provide the subtitles and audio exhibits.

Who We Have Served

    Bob Burcina

    Ret. Police Officer, Sr. Special Investigator, Napa, CA

    "As a senior special investigator in one of the top insurance companies in America, my unit frequently procures the services of Stutchman Forensic Audio and Video Laboratory to clarify and analyze audio and videotapes. We look to SFL to provide the unbiased investigation into our audio and video forensic needs."

      J. Tony Serra

      Lawyer, San Francisco, CA

      "In an attempted murder case, his graphics, aerial photographs, enhancements of video and audio tapes were state-of-the-art. He testified as an expert witness for us in these areas. I heartily recommend Mr. Stutchman to anyone needing his services."

        Roslyn A. Eliaser

        District Attorney Investigator, Santa Rosa, CA

        "Since my first meeting with Mr. Stutchman, I and other investigators in our office have used him to examine both audio and video evidence for purposes of criminal prosecutions. On all occasions we have been exceptionally pleased with Mr. Stutchman's work and continue to use his services. I know I can count on him to provide fair and competent examinations of audio and video evidence."

          Laura M. Petty

          Certified Criminal Law Specialist

          "Steve is great at enhancing video and audio recordings, and he recently deconstructed a fairly complex video compilation created by law enforcement. He was able to tell me what they got right and what they got wrong, excellent material for cross-examination. I will always return to Steve for forensic help."

          FAQ

          Frequently Asked Questions

           No. Our audio forensic services are available to attorneys, insurers, law enforcement, and government agencies only. We do not accept private consumer inquiries or personal audio editing requests.

          Our examinations are conducted and documented with courtroom scrutiny in mind, and our analysts have testified in state and federal courts and in depositions. Admissibility itself is ultimately determined by the court; no forensic provider can guarantee it in every matter.

          911 calls, jail calls, body-worn camera audio, wiretaps, consensual recordings, and most digital audio formats, including proprietary system exports.

          An audio authentication examination evaluates recording artifacts, background noise consistency, timestamps, and metadata for signs of editing or manipulation. The strength of the conclusion depends on the files and technical information available.
