Acoustic Brush
Correction of measurements, especially environmental ones, has always been one of the main features of NoiseWorks.
The use of "Masks" is the preferred technique for eliminating unwanted events from a time history. The effectiveness of masks is beyond doubt, but the main drawback is that artificial elements are inserted into the time history. In the case of a full mask, this is an interruption of the time history, and in the case of a replacement or offset mask, this is an arbitrary value decided by the technician performing the operation.
The new correction tool (we call it Acoustic Brush) borrows from image editing applications the technique of cloning an area and using it to replace another.
The advantage is that the unwanted element you want to eliminate is replaced by noise taken from the same context, normally just before or just after the event itself, which eliminates the unwanted part while maintaining the continuity of the time history.
