I made a fictitious radio spot for a festival. It was a pretty fun activity to do. What I did after writing the script was that I laid out the sound effects and music I was going to use. I then proceeded to mix my vocals. I used a normal 7 band EQ then a 6030 Ultimate Compression plugin and added a pitch altering plugin and threw some reverb over that. I then proceeded to lay down the music bed after vox manipulation and chopped up where I wanted the samples to play. I then lined up the music samples I wanted to use and just went back in and fine tuned some lengths and then added fades. There wasn't anything too difficult about it, but if I were to go back and change something, it'd be the fades in and out and make them crossfades instead. You can check out the spot on my Soundcloud here.
