Request a Confidential Review

When recordings matter, a clear, defensible analysis can help.

Audio Clarification

Can this recording be made clearer? Often, yes. I reduce noise by hand, with repeatable methods — no AI, nothing invented. A diagnostic review tells you what’s realistic before you commit.

Sound Comparison

How do two recordings compare? I analyze their source characteristics using accepted forensic methods and give you a clear, qualified opinion on what the audio supports. You’ll know what’s technically possible before you decide.

File Authentication

Is this recording what it claims to be? I examine the file container and content for signs of editing or alteration. You’ll know where the recording stands before anyone challenges it.

Professional Audio Forensics Services

When audio recordings are unclear, disputed, or questioned, a structured forensic review can help determine what can—and cannot—be reliably heard. Where understanding is essential, I offer two levels of service.

Case Spotlight: John Giuca

Clarifying Low-Level Sounds in a High-Profile Deposition Recording

John Giuca was wrongfully accused of murder and audio forensics helped his case

“The enhanced audio made it easier for our team to review faint background sounds in the recording that were otherwise very hard to distinguish. This gave us a more complete understanding of what was present in the interview and helped us evaluate the material with greater clarity. The analysis was presented in a structured, well-documented way that supported our broader legal review.”
