Rarely does it work out that the recording of a narration comes out perfect. While it may be usable, there is always the opportunity for improvement. While you may not think the audio is anywhere near as important as the graphics you use on your slides, poor quality audio can become a distraction, especially if the volume is too low to be clearly audible.
