Acquisition of Data
Provided your media file or files have not already been procured, we can extract the desired file from the smart phone/tablet/recording device where it is stored, transfer it from tape and convert to a digital file, or, in the case of voicemails, download the desired audio message/messages from the server.
Your Evidence is Secure
We follow established chain of evidence protocol and never outsource any of our work. All processing of audio is done on a digital copy. Once your evidence has been "cloned," we lock it up and don't touch it until we return it to you.
Audio clean-up involves the removal of sound components that are obtrusive or that mask important content, typically dialogue. This process can involve lowering or removing background ambience, reducing traffic noise, suppressing reverberation (i.e. "echo" present in a hall or garage setting), or the surgical removal of specific sounds, such as a car horn or a dog barking. In the case of evidence in legal cases, the goal is typically to achieve maximum intelligibility of speech. In other cases (typically media post-production), the goal more likely is to produce pristine audio with specific unwanted elements removed.
Audio enhancement goes hand-in-hand with audio clean-up and is of particular importance in dealing with files related to litigation or criminal cases. This process involves the use of equalization and filtering which target voice frequencies along with compression and leveling, pursuant to maximizing the intelligibility of speech.
Video and Digital Court Recorder (DCR) File Audio
We can extract, process and re-sync the audio portion of video recordings (creating a new file; we never alter the source video). We can also 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, for obvious reasons.
All File Types Supported
We can work with and/or convert to and from all standard audio and video formats, i.e. wav, aiff, mp3, mp4, m4a, aac, etc. Completed work can be delivered in any desired format, saved to thumbdrive, transfered over a password-protected internet transfer service, or burned to audio CD or, in the case of video, to DVD.
Our chief audio technician is available to testify in Court as to the specific processes applied pursuant to clean-up and enhancement of recorded evidence.
Pick-up/Return of Physical Evidence
We offer pick-up and return of physical evidence, i.e. cell phones, mobile devices, tapes, audio CD's, etc., locally in the Tucson area.
Completed work can be stored on a data CD and archived here for a modest fee (for future reference), or, once your evidence, processed files and report 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 3 months before deleting it.
