Test everything: the location of the microphone, the settings on the microphone, the computer software. Do sound checks and listen closely to that audio. Eliminate ambient sounds: turn off loud appliances, close windows, keep pets away, and be aware of people who may enter the space.
In the first few minutes of recording, keep an eye out for anomalies. On our first take, I peeked at my GarageBand software and noticed it was recording about five seconds of audio, erasing it, then recording five new seconds. Turns out it was in some kind of loop mode. You don’t want to record an entire podcast and then realize you need to do it over again!
Many of us have this habit; I’m no exception. It’s not an issue in normal conversation, but it’s annoying to hear on a podcast. Consider recording a mock podcast with a friend to practice speaking more slowly and deliberately to eliminate filler speech.
This is for a couple reasons. A hard table adds echo to voices. Also, many people tend to touch the table while speaking, and all those vibrations get picked up loud and clear in the recording.
Bantering and casual? Structured and informational? Neither way is more right, it just depends on what you’re going for. I didn’t think about this beforehand, so when the interview became more conversational, I felt unnecessarily awkward.
It’s not as scary as it seems. Pretend that all of one person will ever listen; that takes the pressure off. Don’t hold back just because you don’t want to produce something crappy. If you don’t believe me, listen to Joe Rogan’s first-ever podcast. It’s bad. Record something crappy, learn from it, and keep recording!
