Why your podcast sounds amateur (it is not the microphone)

People upgrade the microphone first because it is the part you can see. It is almost never the problem. A broadcast mic in a bare meeting room sounds worse than a modest mic in a treated one, and no amount of plugin work afterwards undoes it.

What you are actually hearing

Three things make a recording sound amateur, and all three are the room. Reflections off hard parallel walls arrive at the mic a few milliseconds after your voice and smear the consonants. Low frequencies build up in the corners and make everything boomy. And steady noise — air conditioning, a lift shaft, traffic — sits under the whole recording where a noise gate cannot remove it without eating the tail of your words.

What treatment does, in order of value

• Bass traps in the corners — the least visible change with the biggest effect
• Broadband absorbers at the first reflection points, level with your head
• Something soft underfoot; a bare floor is a mirror
• A silent AC run, or at minimum an AC you can switch off for ninety minutes
• Doors and windows that seal, which most meeting rooms do not

Foam squares on the wall behind the camera are decoration. They do almost nothing below 500Hz, which is where a voice lives.

How to check your own room

Stand where you record and clap once, hard. If you hear a short ringing tail after the clap, that tail is going into every recording you make. Then stop and listen for thirty seconds without speaking — whatever you can hear is already on your last episode.

Our floor measures under 0.3 seconds of reverb time and has a separate, silenced AC run, which is the whole reason we built it rather than converting a meeting room.
