Camtasia Studio screencasting software includes an audio enhancement feature, providing the means for reducing noise in audio recordings, such as background noise and the tinny, clipping and clicking sounds that sometimes appear. Voice optimisation editing within the program reduces these sounds even further. Although the Camtasia software eliminates most of the noise, using a quality condenser microphone is the best preventive solution. With the combination of a high-quality recording and Camtasia audio editing, the unwanted noises in the recording disappear.
