For the reproduction of channel-based mixes a standard loudspeaker setup is required, which is impractical for the most listening situations and rarely results in a comparable listening outcome. In contrast, object based spatial audio mixes are a description of an audio scene consisting of sound objects, each fed by a mono input. The rendered audio scene can be reproduced on spatial sound wave listening systems and creates a similar listening experience independent of the loudspeaker setup used.
To experiment with an object-based sound reproduction system, a professional music production consisting of three popular music titles is carried out and mixed down to stereo beforehand. In two experiments, the processed tracks of the stereo mix are used as individual sound objects of an audio scene, thus creating an object-based mix. This adds the new authoring process to the production side, in which the sound objects are placed within the envisioned audio scene. In this context, authoring can be seen as an intermediate step between the usual mixing and mastering process of a music production and is closely linked to the latter. During the authoring process, different approaches and mixing philosophies are used and discrepancies between the common channel-based mixdown and an object-based authoring process arise, showing new ways of creating an augmented listening experience. In this paper, the production process and the experimental authoring process for popular music are described and reviewed.
