What We Do
Turn Unclear Evidence Into Case-Winning Exhibits
You have the recording. But between the HVAC hum, the car engine noise, and the low microphone quality — no one can make out what was actually said. Opposing counsel is hoping you do nothing with this evidence. The court reporter can’t transcribe it. And the jury deserves to hear the truth.
Noise Reduction & Cleanup
Remove hiss, buzz, hum, HVAC, traffic, and wind. Isolate target voices from background chatter. Frequency-specific filtering preserves the integrity of the original.
Forensic Transcription
Certified forensic transcripts with time-stamps, speaker identification, and court ready videos with scrolling transcriptions. Admissible as court exhibits.
Audio Authentication
Detect edits, splices, and tampering. Authenticate whether a recording is continuous or has been altered — critical for challenging or defending audio evidence.
Metadata & Equipment Analysis
Technical research of metadata, equipment identification, and creation method — determining what was used to record the audio and whether it’s consistent with claims.
Speaker Identification
Spectrographic voice ID expert compares audio recordings to identify who is speaking. Detection of AI-generated voice clones and deepfake audio.
Courtroom Presentations & Testimony
Before/after exhibit demonstrations played to jury, AES (Audio Engineering Society) member experts available to testify, play the original and clarifications live in court.

Your Questions, Answered
Common Questions From Attorneys
Can any audio recording be cleaned up?
Most can be improved significantly. The degree of improvement depends on the original recording quality and the type of noise. During your initial paid evaluation, we review a sample of your audio, do initial testing, and give you a clear and honest assessment of what’s achievable before you commit further.
Will the enhanced audio be admissible?
Yes — when done forensically. Every enhancement is documented with chain of custody and a methodology report describing exactly what was modified and why. No AI allowed. We provide both the original and the enhanced version; the jury hears both.
Can you authenticate a recording I suspect has been edited?
Yes. Forensic authentication detects splices, edits, time-stamp inconsistencies, and signal anomalies that indicate tampering. We’ve debunked fabricated recordings and validated contested ones.
How fast can you turn around urgent audio work?
Standard turnaround for work is very dependent on the nature of the job, but 10-15 business days is not unusual. Trial-deadline rush work can be accommodated for a rush fee. Let’s discuss your court date during the conversation with our case manager.
Do you handle AI-generated voice cloning?
Yes. Voice cloning and deepfake audio detection is one of our specialty areas. As AI voice synthesis becomes more common, forensic authentication is increasingly critical. We use spectrographic analysis, metadata, and pattern detection to identify synthetic audio.
