Noise Removal

This processing is very convenient and easy to handle. Basically, it allows to "clean" a sound file from undesired noise or sinusoïds, but is can also be used to transform it, as many treatments in AS. It is based on the estimation of the noise level variation and its maximum, frequency by frequency, in one or several regions of the sound file, or noise zones. This is why one or several noise zones must be defined before proceeding to the removal.
