Over the past few years, as development, testing, and rollout progressed regarding the HD-Radio (IBOC), DAB and DRM transmission systems, audio processing has been one of the key components to augment this new technology. It became apparent that dynamics processing would figure in both the aural and technical performance aspects of these new systems. It has been successfully proven that dynamics signal processing improved other bitrate-reduced audio services like internet audio streaming, especially at low bitrates. This discussion will offer examples of proven methods that demonstrate the benefits of audio processing with these new digital broadcast systems. There are important issues that must be considered, and thought out, or digital radio?s benefits will not be fully realized.
