Audio Tape Enhancement

Audio Tape Enhancement Experts:

Audio enhancement of tape recordings are conducted using a wide range of digital filters to improve the intelligibility of spoken word.
For example, interfering bar chatter and background noise is analysed and reduced then enhancement algorithms are applied to clarify dialogue of near party conversations.
Alternatively, a 999 emergency cassette recording requires background conversation enhanced to assist evidentiary investigations.
The final result is tailored to each client's specification and instruction, whether it be for personal use or evidence in legal presentations.

Enhancement Of Digital Audio Recordings:

Digital recording devices at times produce many unwanted, distracting and obstructing noise interference and frequency distortion artefacts. This in its entirety can cause the recording to be displaced or unintelligible. The following examples are mentioned to indicate where both standard enhancement of a digital recording and the forensic enhancement of digital audio recordings are often required:

  • Clean up dictaphone noise produced by the recording device.
  • Forensic background enhancement on sound recordings to bring forward audible levels of environmental noise.
  • Remove recording device hum frequencies to increase audibility.
  • Enhance conversations to produce more audible content.
  • Clean individual sentences or words spoken to produce more accurate transcriptions.

Dialogue Enhancement Specialists:

In many cases conversation is recorded to assist an individual or organisation in documenting dialogue spoken during a specific scenario or meeting. Depending on where the recording device microphone has been placed the end product can often produce weak, distant, muffled or distorted recordings. Consequently, this produces the need for the recordist to seek professional assistance. At Audio Forensic Services we can assist clients in this matter. Here are some examples:

  • Speech enhancement to improve audibility on audio recordings.
  • Audio cleaning processes conducted to enhance voice dialogue.
  • Levels raised of near party speakers and background interference suppressed.
  • Levels raised of far party speakers to enhance background conversations.
