Abstract
There is described discovery of a plurality of audio devices, and for the discovered audio devices are determined relative positions thereof and distances therebetween. The determined relative positions and distances are used to select a constellation of audio devices from the discovered plurality. This constellation is selected for playing or recording of a multi-channel audio file so as to present an audio effect such as a spatial audio effect. Channels for the multi-channel audio file are allocated to different audio devices of the selected constellation, which are controlled to synchronously play back or record their respectively allocated channel or channels of the multi-channel audio file. In a specific embodiment the determined distances are used to automatically select the constellation and include distance between each pair of audio devices of the plurality. Several embodiments are presented for determining the distances and relative positions.
