aka, how to avoid background noise in your interview recordings:
I Thou Shalt Avoid Interviews In Corridors Where People Walk By
II Thou Shalt Avoid Interviews Windows Facing Busy Car-Humming Roads
III … Avoid Computers That Produce Audible Hums and/or Connect to Noisy Printers
IV … Avoid Large light fixtures, which produce an annoying buzz you may only notice later.
V Large Rooms Are Generally Netter Than Smaller Rooms For Echo-Control.
VI Record AWAY From Walls, Preferably In The Middle Of The Room.
VII Soft Walls – Wallpaper And Wood – Are MUCH Better Than Marble And Other Hard Vibratory Surfaces. Carpet is ideal.
VIII When Conducting Interviews, Nod In Response (Instead Of saying “Yes” or “Uh-Huh”)… unless you want A LOT of “Uh-Huhs” In Your Interview (Who Knows).
IX Rustling Paper, And/Or Flicking Pages Can Sound Lovely And Can Also Sound Irritating. It Depends on Your Aesthetic (Good to Have One More of Less Figured Out First).
X Once You Have Positioned The Microphone, Do Not Move It Unless You Must.
