Trinity Enhance Plus™
Designed specifically for audio forensic use, Trinity Enhance Plus is a stunningly effective audio forensic toolkit comprising six related tools that allow you to suppress noise and enhance speech to increase listenability and intelligibility. It also allows you to enhance the background if that contains wanted detail. It was developed for CEDAR Cambridge to allow lab users to obtain results that are identical with those obtained in the field by users of the CEDAR Trinity 6 surveillance system.
The six processes, each controlled by a single slider are:
Rumble - which suppresses low-frequency noises, typically below the vocal frequencies.
Motor - which removes steady noises such as engine rumble, mains hum, air conditioners, and fans.
Noise+ - an improved noise reduction filter that targets broadband noise more accurately than before.
Hiss - a new hiss reduction filter that suppresses or even eliminates residual broadband noise.
Background - which enhances background sounds to clarify distant sounds and speakers.
Speech - which enhances speech signals relative to other types of sound to help reveal the voices.
The lack of complex controls makes Trinity Enhance Plus quick and simple to use, and allows even novice users to clean difficult material to a standard that would have seemed impossible just a few years ago.
