What is Digital Audio

Audio metadata are an essential tool that supports control and management of systems that create, transmit, describe, manage, and store digital audio. Throughout the lifecycle of digital audio objects—pre-production, acquisition and production, post-production, distribution, storage, transmission, and archiving—metadata “describe the attributes of a resource, characterize resource relationships, and support resource discovery, management, and effective use” (Vellucci, 1999). Technical and structural metadata enable audio in devices and software applications; descriptive metadata provide context. Metadata also relate and incorporate audio in a multimedia environment resulting in profound effects on conception, reception, and consumption.
