AB  - With the increasing number of installed surround sound systems in consumer homes and cars, the demand for surround sound content is rising. However, the vast majority of content is still only available in stereo. Furthermore, it is in many cases difficult to create a surround mix for content previously released in mono or stereo due to the high effort necessary or simply because the original multi-track recordings are unavailable. Consequently the need for tools that allow an automated or semi-automated stereo to surround up-mix is growing. In this paper, a novel approach is described which is based on technology that is part of the MPEG Surround standard. The basic algorithm and some proposed extensions are outlined and potential use-cases described. Finally, the subjective quality of the presented approach is compared to existing solutions.
