Surgical processing
Surgical processing can be used to process short regions (up to 10 sec-
onds) offline. This type of processing is mainly used to reduce, remove or
replace unwanted sound artefacts in the audio material, which can be
done with great precision.
As with all Spectrum editor operations, you first have to define a time/fre-
quency region. Once a region has been set, you can select one of the two
Surgical processing modes. These are as follows:
Filtering operations.
These are described below.
Copy operations.
This allows you to copy a spectrum region and apply it to another region – see “Copy op-
erations” on page 265.
Filtering operations
The Filtering operations allow you to filter a selected region in various
ways. This works as follows:
1. Select the Spectrum selection tool so that the Spectrum editor dialog
opens.
2. Define a region in the Spectrum view.
Make sure that the region does not exceed 10 seconds.
3. In the Spectrum editor dialog, select “Surgical processing (offline)”.
4. Clicking “Process” will apply the filtering according to the set parameters.
See below for a description of these.
