Audio Forensics -- cleaning up bad quality audio and creating transcripts

When you have audio evidence and want to reveal the details of an event, separating and removing or suppressing the noise from the important content can be a delicate process. Our audio forensic process for clarifying audio may involve the following:

Removing hum, buzz, hiss, and other electronic noise
Removal of traffic noise, horns, police or fire sirens
Suppress or remove air conditioner, refrigerator, or car engine noise
Boosting and equilizing specific dialogue to make conversations sharper and louder
Limiting extraneous or unwanted sudden sounds such as gun shots, dogs barking, door slams, etc, in order to allow for other dialogue to be revealed and heard
Minimizing echo
Evening out — lowering the loudest sounds and boosting the most quiet sounds — in order to make a sound file more easy to listen to by our client.

Forensic Transcripts from Audio Evidence, Better Than a Court Reporter

For audio evidence we can provide forensic transcripts in which we document our expert opinion about what is being heard on an audio track. This is more complete than transcripts provided by a court reporter, who often are required to leave difficult to hear audio labeled as "UNINTELLIGIBLE".

Identification of a speaker can be important to a case. In the case of audio, voice identification, or voice ID, may help vindicate a suspect or it may encourage a client’s attorney to settle a case. A standard court reporter might label a speaker as “UNKNOWN SPEAKER”, but a forensic audio expert creating a forensic transcript could be able to identify the individual and label the individual on the transcript — through either witness interviews, critical listening, or computer analysis.
