AUDIO ENHANCEMENT SERVICES,
VOICE ENHANCEMENT

Audio enhancement is a forensic process used to improve an audio recording’s clarity without damaging its authenticity. With access to clear, factual audio information, these recordings can work as admissible evidence in a court of law.

 

At Primeau Forensics, we offer audio forensic enhancement for third-party examination of evidence.

The Forensic Sound Enhancement Process:

STEP #1

Identify the unwanted sounds.

STEP #2

Reduce or remove the unwanted sounds.

STEP #3

Report observations and opinions.

The general scope of the enhancement process includes listening for unwanted sounds, removing them and presenting observations. The sound removal procedure can involve a series of methods for unwanted sounds such as traffic noises and background static.

 

Once forensic audio enhancement experts remove the unwanted sounds, they can enhance the wanted ones, such as speech. At Primeau Forensics, we use industry-standard equipment to ensure we maintain the integrity of the sound. We can use our equipment on isolated audio files or audio in video footage

 

Take a look at some of our methods for forensic audio enhancement.

BELOW ARE SOME OF THE PROCESSES WE USE TO ENHANCE AUDIO RECORDINGS:

CRITICAL LISTENING

Critical listening is the cornerstone of audio forensics. Audio experts have highly trained ears that can pick up crucial audio sections that need to be enhanced. They’ll use noise-canceling headphones and look at frequency ranges and recording levels.

EQUALIZATION (EQ)

Equalization is a process that reduces unwanted frequencies and enhances needed ones. With distracting frequencies removed, audio enhancement experts can perform other procedures smoothly.

DYNAMICS PROCESSING

Compressing the sound raises the volume levels and balances them for clarity. Experts may use compression and gates to boost the sound and reduce any remaining unwanted noise.

Noise and Reverb Reduction

This step is where forensic audio technicians remove unwanted sounds entirely. These sounds may distract from speech and limit the ability to understand the exchange.

 

During the noise reduction process, an expert uses a noise profile to systematically remove the wanted sounds without affecting dialogue or other important signals. They also use tools to reduce echo and reverb that affect the audio quality.
