The guru of Services Drafts Colin Bart Audio Engineering Specialist I'm Colin Bart. An audio engineer based out of Chicago, IL. I have worked on all types of productions, from post audio for television commercials, to podcasts, to recording and mixing up-and-coming artists.When working with me, you can expect an open line of communication. The most important part of being an audio engineer is listening, and that's a characteristic that matters just as much outside of the studio as it does in the studio. Work Terms I'll work and communicate in whatever manner you most prefer! My job is to make your audio production experience easier.
