I hate to tell you this, but you need to get up close and personal with your microphone. Often when a budding podcaster contacts me because he’s not happy with his audio quality, I watch him in action. Most of the time I discover this simple fact: the podcaster is way too far away from the microphone.
Don’t be afraid of the mic! If you’re far away, you’re recording yourself at low volume – by default – and you’re going to have to amplify your sound during the production process. The problem with this technique is that you’re going to end up amplifying all the sound, including the ambient noise of the heating and ventilation system or the air conditioner or the traffic outside your window. Not desirable! It’s much better to start off with nice, clean, loud-enough sound.
My suggestion is to experiment with your microphone. Sit down (or even better, stand up if your mic stand is adjustable) and record yourself as you find the sweet spot in your microphone. I can’t tell you where your particular sweet spot is, because each of us is different, and microphones vary as well.
Also, if your microphone has different settings, like the Blue Yeti, make sure you have clicked on the proper setting (cardioid pattern) if you are recording just yourself.
If you’re like me, and have a habit of popping your plosives, you might want to invest in a pop filter. This will allow you to get really close to the mic without blowing all that air on it and creating an auditory distraction for your listeners.
So, if you’re trying to improve the sound of your voice on your podcast, don’t be afraid to get up close and personal with your microphone!
