Abstract:
In many trials, multimedia materials, video or audio, brought as evidence could make the difference between “guilty” or “not guilty” verdicts. Most multimedia content is stored in a digital form nowadays, therefore, with so many free editing software at anyone’s disposal, it is very easy to be forged. In other situations the critical evidence, even if recorded, it can be heavily masked by other signals and declared inappropriate. This paper is a contribution to the multimedia forensic domain presenting the impact of the acoustic environment on a computer software based on adaptive filtering, which can be used to recover a speech signal drowned in loud music. The results help to decide if placing a microphone in a certain room could be useful or not given the proposed solution for recovering the speech is to be used afterwards.
