Abstract: An apparatus with a base unit comprising a microphone array arranged to capture a plurality of local audio signals for producing a spatially encoded sound-field signal, and a remote microphone device with a microphone and an associated storage portion, wherein the remote microphone device is arranged to capture a remote audio signal associated with a sound source with the microphone and store said remote audio signal in the associated storage portion. The apparatus is further arranged to use the plurality of local audio signals to produce a spatially encoded sound-field signal with a plurality of components, determine a position of the remote microphone device, and generate a spatially encoded soundtrack using the spatially encoded sound-field signal and the stored remote audio signal in accordance with the determined position of the remote microphone device.

Abstract: The invention relates to a method for obtaining a position of a sound source relative to a dedicated reference point. A first and a plurality of second sound signals are recorded which are synchronized in time. The position can be obtained by applying an estimated filter to a correlated signal derived by correlation of the first sound signal with at least one of the plurality of second sound signals in the frequency domain. Two timing values are derived in the at least one filtered and correlated signal exceeding a dedicated threshold in the time domain. Then the distance between the dedicated reference point and the sound source based on the respective obtained first timing value and second timing value.
