Rules and Tips for Spectral Editing by Copy Operations

The Source at Cursor function is recommended for copy operations in the Spectrogram and Wavelet display that are intended for audio restoration purposes. You first define a source region and a destination region, and then you copy audio from the source region to the destination region.

• Setting the source region just before or after the sound to remove can produce very accurate results, as this region probably contains a similar frequency spectrum as the target region containing the artifact.

• In the low to low-mid frequency range, the masking or removal of unwanted artifacts is difficult to achieve without audible interruptions. Finding a limited frequency area is important to not interrupt the flow of the audio when removing artifacts.
