Theater of the mind
I have been listening to radio theater since I was a kid....Stan Freeberg, Dick Orkin, Ken Nordine, Firesign Theater, and the great radio shows of the past, and bring that knowledge of what can be done with sound effects and music to my client's scripts.
Create a :30 or :60 film noir audio track; take a voice-over and put it somewhere.....create theater of the mind.
Compose an original music track using sound effects as musical elements to underscore the message.
Or add a sound effect at just the right moment for emphasis, or as a punchline.
