Audio restoration is a generalized term for the process of removing imperfections such as hiss, impulse noise, crackle, clicks, wow and flutter, background noise, and mains hum from sound recordings. It can be performed directly on the recording medium, or on a digital representation of the recording using specialized software tools. With any project, we consider the condition of the physical media, the anticipated audience, and the cultural moment of the original recording.

Philosophy: We apply processing if the defect is a distraction for the listener. In general, it's better that it sounds natural, so it's better to have an original defect than a new defect.
