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.

The noise removal can be applied to a selected region of the file, even if the noise zone(s) are located outside this region. Select the Restrict to Selection option. If you already selected a time region to process, the begin and end time will be displayed in the corresponding prompt

Suppress Sinusoïdal Noise : sinusoids whose level is lower than that of the detected noise level are removed prior to applying spectral substraction. Suppression Attack Time : a value in ms, which specifies the time constant in ms for the attack of the spectral subtraction filter. This allows to preserve the reverberation of previous sounds for instance.
