Sometimes an audio recording is difficult to understand due to background noise such as traffic, weather, machine noises, etc.

Audio/Video Forensic & Restoration Associates will enhance the audio files so the desired audio can be more easily understood.

Our Expert Associates will implement the process of reducing noise, and increasing desired audio using professional tools within a Digital Audio Workstation (commonly called a DAW.)

Reducing noise from an audio file is a delicate and lengthy process.

In some cases, the audio file is mostly static and we are asked to pull whispers from the file. Most often there is not enough of the voice recorded to enhance the conversation to an audible and understandable measure. This is why it is important for us to analyze audio and video files before enhancement.

Analog forms of recorded material get audio restoration along with enhancement. This is because the analog recording devices generate an electric hum as it’s parts move while recording. Learn more about audio enhancement.
