What are the “Smart editing” tools? What do they do and how do they work?
Muting and cutting are perhaps the simplest means of eradicating short-lived audio artifacts. Both techniques are extremely simple – after selecting a block of samples that contains a disturbance, one may attempt to either mute, or remove, the unwanted part of the signal. If the selected fragment is sufficiently short, and if block boundaries are chosen appropriately, chances are the disturbance will be removed – the effect owed to the inertia of our auditory system and high redundancy of audio signals. The success of the local muting/cutting techniques depends critically on a careful selection of block boundaries. Local muting may introduce discontinuities at both block edges usually heard as clicks. Cutting may also introduce discontinuities (if signal values at both block edges don’t match). Additionally, it may disturb the periodic structure of the processed signals leading to audible distortions of another kind. Basically, local muting and cutting are trial and error techniques –
