Dear user,
The edit tab options are greayed out because there is nothing to Copy/Paste/Delete/Cut or Undo/Redo.
The features Copy, Delete, Cut will be available after you select an area to copy, delete or cut with your mouse coursor on the waveform.
The feature Paste will be available after you copy an object that can be pasted afterwards.
The feature Undo or Redo will be active after you make any changes to your audio.
Please let me know if I can be of any further assistance to you.
Kind regards
