Research & Development


Object-based audio is an emerging paradigm for representing audio content. However, the limited availability of high-quality object-based content and the need for usable production and reproduction tools impede the exploration and evaluation of object-based audio. This engineering brief introduces the S3A object-based production dataset. It comprises a set of object-based scenes as projects for the Reaper digital audio workstation (DAW). They are accompanied by a set of open-source DAW plugins–—the VISR Production Suite—–for creating and reproducing object-based audio. In combination, these resources provide a practical way to experiment with object-based audio and facilitate loudspeaker and headphone reproduction. The dataset is provided to enable a larger audience to experience object-based audio, for use in perceptual experiments, and for audio system evaluation.
