A tip from Ananta on our old forums:
If you have a desktop microphone stand, you can isolate it from the sounds of people tapping on the table, sliding papers, and such by setting the stand on top of one of those older-style thick spongy mouse pads. If you find that you keep blowing into the microphone, or if when you finish a sentence and close your mouth, suddenly you let out the rest of that breath in a blast into the microphone from your nose, then reposition the mic so that it is just above your nose level, aiming the pickup area slightly downward.
Definitely if there are hard, close-in echoes cluttering up your recordings, the walls of the room are too bare. Even temporarily hanging blankets or quilts or some other kind of baffling around the place where you, guests, and microphone are, will help to eliminate them. Some people will go into a closet to take advantage of all the fabric clogging the space, to do their solo recording.
Event recording, you can obtain inexpensive shotgun microphones designed for video shooting, even some stereo ones.
For a group around a table, often a “boundary microphone” (or two if a long table, or if two tables of opposing arguers) will be the best option. Again, some isolation from the tabletop is a good idea.
