Being on air can be intimidating at first, but let me tell you that it's a lot easier than you'd think. Maybe not easier, but I find that there's way less pressure talking by yourself or with another person or two in the room than there is talking or performing on stage or in front of a camera.
Being on air, oddly enough, is not what I originally attended the BCIT Radio Arts and Entertainment program for. BUT, I've actually grown accustomed to it and grown to enjoy it too.
Also, the production side of the performance! Adobe Audition, which is the software we use to piece together audio clips with music and sound effects, can be a little confusing at first. But practicing really helps and it actually gets to be a lot of fun!
