USA vs Wheeler

We were assigned by Judge Katz of US District Court in Toledo, Ohio.

Our task was to take control of all discovery evidence inclusive of approximately 300 hours of audio (cassette tapes) to enhance and convert them to digital format. As well as, 30,000 pages of documentation which needed to be scanned into a computer to make a searchable data base.

There were approximately 30 defense attorneys who could request from us any or all of the audio and documentation.

We were essentially the librarians of this case.

During the actual trial, at times, the attorneys would come to our facility and stand in line to get their enhanced audio and documentation from us.

This was a project that carried over 2 years.

In terms of enhancing audio from a cassette tape, it is typical that these recordings automatically have a residual hum resulting from the mechanical movements of the recording device’s parts as it records.

Other noise in the background that would need to be reduced in an audio recording would be from a multitude of sources such as a running air conditioning or furnace, natural sounds like wildlife and weather, and human activity like other conversations or traffic.

The amount of audio recordings in this case is not typical for most audio enhancement projects.

Each recording must have a unique noise reduction profile unless the recordings were recorded in the same place with the same equipment and typically during a consecutive recording session.
