Creating Object-Based Stimuli to Explore Media Device Orchestration Reproduction Techniques

Media Device Orchestration (MDO) makes use of interconnected devices to augment a reproduction system, and could be used to deliver more immersive audio experiences to domestic audiences. To investigate optimal rendering on an MDO-based system, stimuli were created via: 1) object-based audio (OBA) mixes undertaken in a reference listening room; and 2) up to 13 rendered versions of these employing a range of installed and ad-hoc loudspeakers with varying cost, quality and position. The programme items include audio-visual material (short film trailer and big band performance) and audio-only material (radio panel show, pop track, football match, and orchestral performance). The object-based programme items and alternate MDO configurations are made available for testing and demonstrating OBA systems
