For more than 20 years, CEDAR Audio and its dedicated forensic division have been assisting the law enforcement and intelligence communities in areas such counter terrorism, drug enforcement, customs and border control, and military intelligence, as well as air and marine accident investigation. Recently, the company say increasing use of its forensic products (e.g. CEDAR Cambridge Forensic System) in live surveillance, so they decided to design a dedicated system that offers all the tools needed for officers and agents engaged in this field.
CEDAR Audio understood there was no solution that combined long-term audio monitoring with powerful real-time speech enhancement, recording (with durations measured in years rather than days), event logging, and file verification that ensures that no-one has tampered with the recordings.
CEDAR Trinity allows users simultaneously to monitor, enhance and record up to eight channels of audio. The recorder is an invisible part of the system and is always active, even when the machine is asleep or no user is logged in. To protect against lost data, it will automatically resume recording after a reboot or when the user turns the computer on. You don’t even need to stop recording to listen to previous events. CEDAR Trinity allows listeners to return to times of interest, to loop sections of audio while enhancing the speech, and to log or transcribe these events while it continues to record. Then, the system allows the user to ‘catch up’ gradually with real-time events so that nothing is missed.
In order to allow several listeners to access each of the live feeds, and different people monitoring events as they happen, while others inspect past events of interest, CEDAR developed Trinity Satellite systems that can be connected to any CEDAR Trinity host. The solution allows several users to monitor the incoming audio and perform real-time speech enhancement, or to listen to and enhance past events for logging and transcription.
For evidential purposes, CEDAR Trinity also offers a separate verification utility that can check the integrity of any project or archive. To ensure that everyone authorized can access its features, the user interface has been made as simple and intuitive as possible. Surveillance personnel and transcription experts need no detailed knowledge of recording or enhancement to monitor and extract the maximum intelligibility from any part of an audio stream or CEDAR Trinity recording.
