Move Your Mic Closer: The Free Fix for Echo and Thin Audio
The most common audio problem I hear on consults is not a bad microphone. It is a good microphone sitting too far away. Here is the fix, and why it works.
If I had to name the one audio fix I make most often on calls, it is this one.
Move the mic closer.
Not a new mic. Not a plugin. Not soundproofing. Just closer.
What I keep seeing
An estate planning attorney had her mic tucked behind her keyboard, a couple of feet away, in a room with a little echo. I asked her to pull it in to about six inches from her mouth, even if it showed in the shot. It was better instantly, before anything else changed.
Another attorney had just recorded his first podcast episode and it went badly: echo, a thin sound, and lag. His mic was far away and not facing him, and his video app was quietly using the laptop's built-in mic instead. We picked the right input, stood the mic up facing him and moved it in close. His audio was cleaner and sharper right away, in time to re-record the next day.
A financial advisor told me a friend had said his audio was not right, even though he was paying for editing. His mic was about two feet away. No amount of editing fixes that.
Why closer works
Your voice leaves your mouth and goes everywhere. Some of it goes straight into the mic. The rest bounces off the desk, the walls and the window, and arrives a split second later. That second arrival is the echo.
The closer the mic, the louder your direct voice is compared to the bounce. At two feet, the mic hears the room. At six inches, it hears you.
That is also why turning the gain up does not help in an echoey room. You just turn the room up with you.
"But I don't want the mic in the shot"
I hear this a lot. One live-stream producer I know started out firmly against seeing a mic on camera. Her room had tall ceilings and a busy household, and the far-away mic picked all of it up. She moved to a broadcast-style mic close to her mouth, visible in frame, and now happily calls herself a show-the-mic person. The sound was too good to hide.
If you really want it out of frame, a boom arm that comes in from below or the side gets it close without covering your face.
The two checks before any new gear
- Is the right mic selected? Look in your video app's audio settings. Many people have a good mic plugged in while the laptop mic does the work.
- Which side do you talk into? Some mics take sound from the top, some from the side. Talk into the wrong end and it sounds distant no matter how close it is.
Then close the gap. Three to six inches is the sweet spot for most mics.
