Audio for Video CHAPTER 10 this is a reminder that the room tone will depend on its size, shape, carpet- ing, drapes, easy chairs, and similar factors. where there are no reflections, as in open spaces away from buildings or other hard surfaces, the resulting sound will seem dead. the only way we can simulate dead surroundings within a building is to use carefully positioned sound-absorbing materials. on the other hand, if there is too much reverberation, the result is a confused mixture of sound that reduces its clarity. in practice, the appeal of many sounds can be enhanced by adding a certain amount of real or simulated reverberation to them. today, the most commonly used method of adding some "liveness" is to use a reverberation unit that digi- tally stores the sound and is selectively reread over and over to give the impres- sion of reflected sounds. 257 10.33 PROGRAM MUSIC the role of music in television programs is so established that we don't need to dwell on it here. musical themes often remain in the memory long after the program itself has faded from the mind.
