Digital Audio Workstations
What was once considered a luxury has become a necessity. Digital audio workstations have proven to be a valuable part of any station's production equipment list. While the power and flexibility of these silent workhorses has increased, the relative costs have declined; a plus for the end user. In addition, the systems have become more specialized. Some are designed for large-scale work; others are designed for fast editing of two tracks. Some started in the professional arena and now offer reduced-feature versions, while some started as high-end consumer applications and have become enhanced along the way. Regardless of the paths they took to become the systems they are today, the variety of features and price points are sure to offer something for everyone.
Chances are good that your facility already has some kind of digital editing in use. There are some shareware programs available that offer basic functions. It may be that these suit the immediate need. Frequently, once the convenience of a digital system is understood, the demand for more functions, better effects and faster speed quickly follow.
Most DAWs can fit into one of two categories: computer-based and dedicated hardware. The dedicated hardware designs have a computer at their nerve centers, but they are not usually built around a typical computer operating system, such as Windows or Macintosh. Each method has its own unique set of operational characteristics and advantages.
Dedicated hardware systems tend to be self-contained devices, with the transport, editing and storage components built in. These systems may use an external monitor or have a built-in display. Some may look like computer-based systems, but they do not rely on a host computer for the user interface.
These specialized systems have the advantage of serving a singular purpose. Because they are optimized for a specific function, they tend to be fast and efficient. The proprietary operating system has one major advantage: users will not load games, extra programs and screen savers onto them, saving an extra maintenance call.
The biggest advantage to computer-based systems is that they provide a familiar user interface. Users already familiar with the computer's operating system will feel at home with the same mouse clicks and keyboard shortcuts that they already know.
Equipment networking is an important consideration for any equipment purchase today, but this is no longer a problem with DAWs, because most are able to connect to other devices in some way. Most now offer a standard communications port, typically Ethernet or USB. The systems that offer some other format can probably be interfaced without excessive trouble.
The networking capability is important to facilities with multiple editing stations. Files and projects can be shared between systems and libraries of sound effects, music beds and often-used material can be accessed as needed. In addition, completed productions can be saved to the on-air playback system in a single step. The system's networking may even support ancillary data relating to the audio file, such as a file name and other pertinent information.
