Foenics - FPI's - Artefact-Removal
Artefact-Removal can remove almost all kinds of artefacts degrading the intelligibility of a speech recording. It is very easy to handle, because the implemented adaptive algorithms will do "the job" automatically.
The user only has to adjust two parameters manually - the sensitivity of the artefact removal is adjusted by the 'Threshold' parameter, and the 'Contraction' parameter sets the amount of removed artefacts. This offers the possibility to enhance the intelligibility and listenabilty without affecting the desired signal.
The adjustments of the user parameters are simplified by the display of the number and length of eliminated artefacts. The ability to listen either to the removed or restored signal offers great advantages for the forensic analyst. This function could be used in real-time for an optimal parameter adjustment, or as an analysis of the artefacts.
