Abstract
A spatial audio signal is received that is associated with a microphone array configured to provide spatial audio capture and additional audio signal(s) associated with an additional microphone, the additional audio signal having been delayed by a variable delay determined such that common components of the spatial audio signal and the additional audio signal(s) are time aligned. A relative position is received between a first position associated with the microphone array and a second position associated with the additional microphone. Source parameter(s) are received classifying an audio source associated with the common components and/or space parameter(s) identifying an environment within which the audio source is located. Processing effect ruleset is determined based on the source parameter(s) and/or the space parameter(s). Multiple output audio channel signals are generated by mixing and applying processing effect(s) to the spatial audio signal and the additional audio signal(s) based on the processing effect ruleset(s).
