Built for the witness stand. We extract critical speech from intrusive background noise using deterministic, Time-Variant Spectral Subtraction. No Generative AI. No guessing. Just reproducible, peer-reviewed digital signal processing that survives strict Daubert challenges.

To prove our software does not destroy evidence, we provide the court with three tracks: RAW (A), DELTA NOISE (B), and CLEAN (C). The Delta Track contains the exact static removed from the file. If opposing counsel cannot hear human speech in the Delta track, they cannot claim we deleted the suspect's voice.
Acoustic Challenge: High-momentum echo, static and analog cellular dropout obscuring key dialogue during surveillance.
Acoustic Challenge: Dense, flat VHF aviation static masking low-amplitude, calm vocal transients in cockpit recordings.
Acoustic Challenge: Modern body-worn cameras suffer from intense clothing friction, unpredictable wind buffeting, and erratic kinetic movement masking suspect or witness admissions.
As machine learning and Generative AI increasingly populate the commercial audio processing market, the forensic admissibility of digital audio evidence is under unprecedented threat. Generative models operate on stochastic principles—hallucinating missing audio data to produce subjectively pleasing results—which fundamentally violates the principles of forensic evidence handling. The Acoustic Axiom Engine eschews artificial intelligence entirely. This paper outlines our non-stochastic, mathematically deterministic methodology utilizing Time-Variant Spectral Subtraction and introduces the Digital Null Test as a verifiable proof of evidentiary integrity suitable for federal and state evidentiary hearings.

Whether you need immediate algorithmic enhancement for an ongoing investigation or full expert testimony for trial litigation, we tailor our involvement to your case requirements.
For independent investigators, examiners, and pre-trial analysis requiring auditable speech extraction.
For high-stakes civil and criminal defense requiring live courtroom authentication and Daubert hearing defense.
Dedicated processing pipelines and standing expert advisory for DA offices, public defenders, and large firms.
Technology alone cannot defend evidence on the stand. Acoustic Axiom is supported by an advisory board of certified forensic audio examiners with credentials spanning every major digital forensic realm. If your case requires live testimony, we provide comprehensive lab reporting and expert witness services to authenticate your evidence before a judge or jury.
Upload your contested media file. Before the Daubert-compliant extraction begins, the Acoustic Axiom engine automatically secures your chain of custody and verifies the physical integrity of the recording.
Instant MD5 and SHA-256 hash generation upon upload to legally lock and verify your file's chain of custody.
Automated software scan for digital clipping, DC offset errors, and physical splice-tampering markers.
