It's gotten to the point where I'm horrified to see a cart machine in use at a radio station. Just about every feature we have appreciated in the broadcast cartridge has been replaced by a more flexible and better-sounding alternative. The economics are such that a digital delivery system is not only preferred but is necessary for the efficient operation of a radio station.

The most important function of a standard digital audio delivery system is spot and music playback. Systems built around this function are typically the centerpiece of modern studio operations. Most systems offer options or features to accommodate on-the-fly playback of elements like beds, jingles, bits, etc., but most are designed to simplify the core studio operation and offer greater reliability. Each system is unique and is adjusted to match a station's specific needs and the talent's requirements. For this reason, there are no solutions that would apply everywhere. System design, installation, and execution depends on the expertise of people who know the operation to select the appropriate system and adapt tools and modules available in a given brand of system. As the station engineering manager, you are in the most unique position to perform these tasks and release the potential of new technology.

Recent developments in audio and data delivery have put pressure on suppliers of delivery systems to expand their options and interconnectivity to accommodate audio streaming, spot insertion, and interactivity. Many systems offer control and voice tracking from remote locations like affiliated stations or remote broadcast sites. Most companies now offer, or are working on, solutions for these issues and much more.

It's fortunate that there is a wide variety of choices available with a wide range of features and price points. You should be able to find everything you need for your station through these companies and even discover new ways to make your life easier. The list of systems outlined here is comprehensive but not complete. You should contact the manufacturers or your broadcast equipment supplier for more information.
