Hello, I am an artist and I record voice overs for Covoco for a story naration. I'm after some tips on the best way to record a clean voice over without the use of a recording booth. I have a decent mic (Rode NTG-3) which records great audio. So I'm looking for tips on ways to isolate exterior sound. Record in a cupboard? Build a soundproof booth out of blankets? Record under the house? Any help will be appreciated. Thank you.
