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.

Abstract: A method to merge data recorded using a wireless external multi-microphone system is described. The method includes determining a communication delay between a mobile device and an accessory device. In response to activation of a camera application, an activation indication is sent to the accessory device and, in response, the accessory device starts recording audio. In response to a camera event, a camera event indication is sent to the accessory device. The camera event includes starting a video recording, pausing/resuming a video recording, ending a video recording or taking a photograph. In response to receiving the camera event indication, the accessory device creates a marker corresponding to the reception time. The method also includes receiving, at the mobile device, the audio data and the marker; and merging image data and the audio based on the marker and the communication delay. Apparatus and computer readable media are also described.

Abstract: An apparatus including a microphone array and a removing system. The microphone array includes a binaural microphone system having first and second transducers, and a voice microphone system having at least one third transducer. The removing system is configured to remove, from signals created from the binaural microphone system, components corresponding to sound of a user's voice sensed at the at least one third transducer.
