Consumers now have audio playback systems that stretch the limits of program dynamics.
Today's listener is able to hear subtle differences in level and distortion within program material and make critical program choices based on the quality of his or her experience. Now it is more critical for the engineer to obtain the maximum loudness with the minimum distortion components in order to fully exploit the dynamic range available in todays digital audio, film and video productions. It has also become of paramount importance that a reliable method of monitoring is used to establish the maximum safe level at which a system can operate. Every Dorrough Audio Level meter simultaneously shows three dimensions of program material content. The meters are easily viewed while providing high precision indications of program energy content.
