Other important restoration processes
In addition to the obvious audio restoration processes, there are some that are equally important but don't fit into any other class. Most restoration systems will have one or more of these installed because everywhere you look you'll find buzzes, hums, clipping caused by unwanted signal levels, and even timing errors on stereo or multi-track recordings.
The processes:
- Removing buzz
- Removing clipping distortion
- Removing 'wrapping' distortion
- Correcting wow and other speed errors
- Changing the duration without affecting the pitch
- Phase correction
