That's funny because I get errors in my digital copies when I keep making copies from copies. DNA has the same problem.In which case you'd be wrong AGAIN!!!! These days, you can make as many digital copies of a sound recording that you want that will be exactly alike.No sound engineer here but I would assume every copy of copy is going to experience some deterioration in quality.
Depends on the quality of your recording equipment, I reckon....
Not sure if this is what RodISHI was getting at or not.
Maybe what you are talking about is making copies from an original.
