I made a #ds106 radio bumper, my first (already have an idea for the second)!
I kind of cheated, because most of the audio was recorded and mixed by a professional at a real studio back in 2001 (backstory and original audio clip here). Incidentally that was before I ever became a teacher. I don’t ever really sound like that in a college classroom.
All I did was drag that mp3 into a new GarageBand project, plug in my USB mic, and record myself saying “listen to your ds106 radio” on a new vocal track. To get the echo I added the Vocal Reflection to the recorded track. Then it was as simple as selecting Share > Send to iTunes from the menu bar. Since I had pre-set iTunes to import audio as a 64-bit stereo mp3, that’s what I got. In iTunes, I right-clicked the new file and chose Reveal in Finder, dragged it to my desktop and uploaded it at http://www.dropitto.me/ds106. I’ll be stoked if I actually hear it on #ds106radio!
