I have a ATR2100x-USB mic from audio-technica. I've been recording some tutorial videos and overall like the sound quality.
But the inherent sensitivity of the mic picks up a lot of residual mouth noises. Like inhaling, exhaling, smacking, swallowing etc.
Is this a problem of mic placement? Audio settings? Lack of dampening equipment of some kind?
Not sure how to begin trouble shooting this problem.
There is some good advice here : https://training.npr.org/2017/01/31/the-ear-training-guide-for-audio-producers/#recording
How to avoid mouth noise:
Changing mic placement can often help, especially if you are using a shotgun mic.
Sipping apple juice is known to work well, as are eating Granny Smith apples. Remember that water can make this problem worse, as can coffee and milk-based products. Not everyone can keep apple juice on hand with them in the studio or out in the field, so you may want to advise your guests to avoid coffee and milk products prior to the interview.
How to fix mouth noise:
If you have a recording with egregious mouth noise, the de-crackle plugin included in Izotope RX can reduce the problem. Sometimes spectral repair tools can also work (you can find those in Izotope or Adobe Audition). That said, it may be helpful to seek the assistance of an audio expert.
