I'm sound designing for a production of The Nerd, and there are many sequences in the show that involve answering machine messages. Since the show is set in the 1970's, the messages are recorded on tape, and thus have to sound like they're on tape when they are played back. What's the best way to make it sound like that? Is there a good EQ setting to use? Good plugins? I'm recording the voice using a Rode NT1-A condenser into Reaper. Ideally any solution would be free, as I know there are plugins from Waves and others that exist, but are expensive. Thanks!
