Audio Processing Equipment

Forensic audio recordings are collected from a variety of sources including telephone taps, in-place concealed microphones, body-wire recorders and transmitters, directional microphones and video recordings. Hum, room noises, acoustic resonance, muffing, restaurant noises, background music, and street noise obscure voices on such recordings. In order to make the voice more understandable, the audio is played through digital adaptive audio filters to reduce or remove the intrusive background noise. Swiss-Impex offers a wide range of One-channel and Two-channels Digital Adaptive Filters
