I am using my Zoom H4n recorder with a rented Rode NTG-8 shotgun mic. So far, my results have been very noisey. Below is an example of the audio without any changes, and the second example has some amplification and noise reduction in audition. I was indoors when this audio was captured, and there was little to no noise in the house. This is my first time using a shotgun with my H4n, so any feedback is appreciated.
Edit: I should clarify. My question is more about what settings I can change on the H4n to reduce noise, rather than fixing it in Audition.
With no changes:
