The current trend in facility design involves two major components to complete an on-air system. One element is the audio routing and mixing functions, which are becoming increasingly tied together. The other is the audio storage and playback system, commonly referred to as an automation system. From the humble beginnings as a way to provide unattended playback of scheduled material with various mechanical methods, today's automation systems are computer-based and provide much more than just audio playback.
What has long been called an automation system was at one time singular in function; it now actually handles various automated tasks. The primary function is content management: storage and playback of audio files on demand. Add to this the ability to load schedules and apply certain rules to fill time automatically and you describe nearly all the systems available today.
While audio storage and playback are still the key functions, an automation system has actually shifted its primary function to become a facility event controller. Through event triggers, such as contact closures, serial data strings and other control paths, the automation system is able to automatically record audio feeds or capture audio files and control external equipment such as audio processors, routing switchers and satellite receivers.
WAN, LAN, thank you ma'am
The need for interaction, control and insertion from a distance has become important, as have WAN-based media sharing and the ability to manage multiple stations from a central site.
Computers excel at storing and manipulating data, so affecting audio data is a natural function. However, new data needs have become important for stations. Program-associated data (PAD) — the basics of song title and artist name — are being used today to feed RBDS encoders and station websites with “now playing” information. This data will also be transmitted on an IBOC stream. With plans to provide radio receivers with more detailed displays, additional data can also be provided, such as an artist's concert dates and information about the performer. Similar added data can be applied to commercial audio files as well.
This data can be tied to audio files and delivered on a schedule through the automation system. The PAD information is likely already part of the stored audio file, so retrieving it for on-air delivery is not a complex matter. This data may be a part of the audio stream or a separate data stream.
The supplemental PAD, such as concert dates or artist news, can also be stored and retrieved as needed. Most systems already have the capability to provide live copy with any audio file. This live copy is simply stored data. Not to over simplify the idea, but data is data to a computer, regardless of whether it is fed to an in-studio monitor or made available to an RBDS stream.
Multi-channel audio is a developing technology for IBOC. There are currently two ways it is being developed. The Tomorrow Radio project, a joint effort between NPR, Harris and Kenwood, adds a supplemental audio channel (SAC) in addition to the main channel so that two program streams are created. Most automation systems can handle more than one program stream, although it is preferable to have a separate workstation to provide the second stream as backup. The other form of multi-channel audio of IBOC is surround sound. While still dealing with audio data, surround-sound files will have a different format than traditional mono or stereo files. Systems vary in this capability today, but it is something to keep in mind if your station is considering an IBOC roll-out with an eye to the leading technology.
