Recording our voices separately makes the biggest difference in the sound quality of an interview. The easiest way to separate our voices is to wear headphones when we chat. Even the basic headphones and mic that came with your cell phone are enough to avoid hearing each other in our recordings.
The audio recording I make separates each side of the conversation, but sometimes things garble. When we chat, I’ll ask you to record yourself locally, too, and send me the file afterward (if possible). Don’t worry—I’ll show you how once we start talking.
