Audio Insert Editing
Audio insert editing, also known as audio dubbing, works the same way as video insert editing. The only real difference is that instead of replacing a section of video with new pictures, a section of audio is replaced with new sound.
Most video machines which are capable of insert editing will allow you to insert video and audio at the same time, so you have the option to simultaneously replace both pictures and sound if you like.
Again, you should consult your operating manual for detailed instructions.
