DeHiss Plus is a wideband noise reduction utility based on a standard noise model. You can use it when a noiseprint is not available. If noise characteristics are time-varying DeHiss Plus may yield better results than DeNoise Plus - being less selective it is also less sensitive to changes in the noise profile.
Even though DeHiss Plus was not designed to cope with impulsive disturbances, it is capable of reducing clicks (small clicks are completely eliminated in the process of removing wideband noise; the large ones are reduced in size).
In order to use DeHiss Plus proceed as follows
1. Indicate the source soundfile by clicking the corresponding SOURCE
button.
2. Choose the DeHiss Plus command, accessible from the Restore menu, or click the DEHISS
button situated on the toolbar.
3. Adjust the four renovation parameters (gain, smoothing range, frequency carving and frame size) and two dynamic noise reduction parameters (noise floor and adaptation rate). Select the range of processing (all, window, block).
4. If desired, change the name of the destination soundfile (only for unregistered source soundfiles).
5. Click the Process button to start processing.
