The Los Angeles Police Department Technical Investigation Division (LAPD TID) has purchased a Cedar Trinity Enhance system and is now using it as one of its law enforcement tools.

‘I use Trinity Enhance for situations ranging from reducing cell echo to street noise to the audio that goes with in-car video,’ says Technical Specialist Steven Ching. ‘We have other tools, but I like that Trinity Enhance has four separate processes in a single application, and that I can control these simultaneously with just four sliders. This makes it particularly versatile, and it works for many of the situations that we have to deal with. If I didn’t use Trinity Enhance, I would have to run multiple apps from elsewhere.

Cedar Trinity Enhance is simple-to-use but effective audio forensic toolkit comprising four related processes that suppress noise and enhance speech to increase listenability and intelligibility. The processes are Motor (which removes steady noises such as engine rumble, mains hum, air conditioners and fans); Noise (which reduces broadband noise); Background (which makes background sounds appear louder relative to the foreground) and Speech (which enhances speech signals relative to other types of sound).

‘As an LAPD technical specialist, I testify in court in cases involving cell phone forensics and video from CCTV; but after cleaning up our audio with Trinity Enhance, we don’t usually have to take the evidence to court. We can present it to the suspect, and that’s often enough.’
