This study examined the digitalisation of broadcast audio data, using Radio Taiwan International (RTI) as a case study. The study was intended to clarify and interpret how RTI constructs digital systems for broadcasting audio from environmental and corporate perspectives. In addition, the opinions of experts were collected using the semistructured in-depth interview method and indirect observation, to synthesise the directions of system constructions and future applications for audio digitisation. The overall result provides a digital archive reference for domestic radio broadcasters by (1) emphasising corporate institutional characteristics, (2) constructing a complete information technology infrastructure, (3) implementing digital media asset management, (4) developing detailed metadata, and (5) creating value-added e-service and cost benefit for digital archiving.
