Audio and Video Evidence Is Crucial

Through the use of image clarification, AVFL improves the quality of video surveillance tapes and digital video files. Clarification involves digital techniques that can reveal detail from shadow or blurry images. We stabilize and enhance Cell Phone and TASER video clips. Through the use of Super Resolution technology we dramatically enlarge a degraded image so that it becomes valuable evidence.

For audio, sophisticated computers and algorithms process the noise out while enhancing the voice. Intelligibility is greatly improved. Near and far speakers can then be understood and identified. Artifacts introduced by recording and re-recording are removed.

Tape and Digital Image Authentication: With sophisticated computers we examine digital audio, digital video, media from mobile devices such as the Apple IPhone and IPad, TASER CAM video clips and wiretaps for tampering. We examine audio and video tapes through test instruments and tape microscopy for authenticity.

Equipment and Software

AVFL uses the latest digital audio video enhancement tools available. Featuring tools developed at NASA and the CIA, and audio tools utilized by the FBI, Secret Service and DEA, we put the power of the federal government and the skills of trained forensic examiners to work for civilians, local police and the entire professional investgative community.

AUDIO EVIDENCE

Audio Restoration
Audio Clarification and audio evidence cleanup. Sophisticated computer algorithems identify voice and non-voice content and process the noise out while enhancing the voice. Intelligability is greatly improved. Near and far speakers can then be identified. Artifacts introduced by recording and re-recording are removed. Transcriptions can be made and linked to CD copies of the final product.

Forensic Audio Examinations and Authentication
Scientific Examination of recordings for alteration, omissions, editing, tampering, recorder actions ie. stop/start/pause/voice activation. Analysis determines that a particular machine was capable of making the recording offered in evidence. Originality is examined. Speakers are identified. Voice and Non-Voice Signal Analysis is performed and samples are plotted on a spectrum analyzer; waveforms are compared and printed. Voiceprint Identification examinations conducted.

VIDEO EVIDENCE

Clarify Dark Footage
Crucial details are hidden in video due to poor lighting, improperly adjusted and maintained cameras and cheap video equipment. Super Resolution technology can reconstitute lost details from cell phone and low resolution IP surveillance video. We can compensate for the poorly exposed video by analyzing the entire video, or just a region of interest to adjust brightness, contrast and gamma to bring out more detail. We can remove noise and video graininess. When the target remains still for even a moment, video noise and other transient items like rain and snow are removed, revealing the details hidden beneath.

Authentication
Authenticity examinations are conducted to determine whether video recordings are original, continuous, unaltered, and consistent with the operation of the recording device used to make the recording.
