I have a Steingerg UR12 USB audio interface with a Takstar SM-1B microphone. I'm using a Mac and Audacity to record the audio. I've been doing voice-overs for over a year now for a software company teaching English. If you need something similar or maybe something unique then just let me know. I'll ensure the audio has no background noise, it's loud and clear, and in a format of your choosing.
