AUDIO RIDER™ AUDIO MANAGEMENT SYSTEM Audio Rider was sold to cable television stations to automatically control the sound volume of all programs sent out over the cable to subscribers. Program volume was made consistent from channel to channel and from program to commercial. Unusually loud programs or commercials were significantly quieted, and volume-too-low programs were made louder. In the middle range, spoken conversation was made the same volume on all channels. This product encompassed a significant number of technical challenges essentially requiring a computer to listen to cable television and decide if the "program content" was intended to be soft, loud, or in between. Future alternative uses for the fundamental algorithms and method of FFT analysis of digitized sounds used in this product are being evaluated for other applications.
