Voice enhancement
We take great pride in improving the quality of audio to help clarify valuable pieces of audio evidence.

The goal in forensic audio enhancement is to audibly discern what is being said by certain individuals so that audio, previously obscured by noise, can be heard and understood.

The success of the enhancement process depends on several factors
  • What the client is looking to obtain
  • Presence of noise
  • Level of compression
  • The quality of the original recording
  • Amplitude of recording
  • Masking elements

Typical cases could include - covert audio recordings, interviews, audio captured from cloud based CCTV systems, audio captured from local DVR recordings, and audio captured from cell phone recordings.

What we can enhance

During an audio recording its possible that environmental and digital noise can inhibit the listener from understanding the audio information captured. In order to help our clients, we can attenuate unwanted noise by using advanced adaptive filters and processing techniques to bring inaudible information out of the recording.
