Services Overview

Acquisition of Data

Provided your media file or files have not already been procured, we can extract the desired media from the smart phone or recording device where it is stored. Voicemails can be downloaded from the server and preserved. Finished files can be delivered in a number of ways as per customer preference. (See All File Types Supported below.)

Security

We follow established chain of evidence protocol and all analysis and processing of media is done on a digital copy. We use a password-protected internet-transfer service for delivery of files electronically.

Analog to Digital Conversion

Virtually any type of analog content, i.e., cassette, reel-to-reel tape, etc., can be safely transfered, digitized, any desired cleanup and enhancement performed and delivered in any format. (See All File Types Supported below.)

Audio cleanup

Audio cleanup involves the removal of sound components that mask important content. In legal cases or disputes, the goal typically is to achieve maximum intelligibility of speech. In other, for example, media post-production applications, the ability to target and delete specific sounds is of particular value, since it is now possible to produce pristine audio with specific unwanted elements removed.

Audio Enhancement

Audio enhancement goes hand-in-hand with audio cleanup and is of particular importance in dealing with files related to litigation or criminal cases. This process involves the use of filtering, equalization and compression pursuant to maximizing the intelligibility of speech.

Authentication of Digital Audio

Owner/chief engineer Eric Westfall is certified as having completed the forensic audio authentication course offered by the National Center for Media Forensics at Colorado University, Denver, and is qualified to authenticate digital audio files.

Video Resolution Enhancement

Video can be enlarged and resolution-enhanced through pixel analysis, either via AI-powered algorithms or, depending on the case, a "forensically valid" software system designed specifically for law enforcement and admissibility in court.

Editing

We are a full-service audio/video editing facility and can assist in preparing evidence for formal presentation.

Digital Court Recorder (DCR) Files

We can extract and process audio recordings from Digital Court Recorder (DCR) files; however, it is not possible to re-import that audio into the DCR format. This is not for a lack of technical prowess, rather, DCR recorders are designed to affix a time stamp in real time during the recording process and these files cannot be altered.

All File Types Supported

We can work with and/or convert to and from all standard audio and video formats, i.e. WAV, mp3, aac, mp4, m4a, MOV, etc. Completed work can be delivered in any desired format, saved to thumb drive, transferred over a password-protected internet transfer service or burned to CD or DVD disc.

Quotes and Reports

We may require a nominal fee in some cases to evaluate a media file and offer a quote. If applicable, delivery of finished work includes a report detailing the processes performed on the audio or video. A formal and signed expert witness report can be produced for an additional fee.

Expert Testimony

Owner/chief engineer Eric Westfall is available to testify in Court as to forensic analysis done or specific processes applied pursuant to cleanup and enhancement of digital evidence.

Archiving

Completed work can be stored on a data CD and archived here for a modest fee for future reference, or, once your evidence and processed files are securely in your hands, erased entirely from our computers if that is your preference. Barring either of the above, we nominally keep files related to your work on our hard drive for 6 months.
