摘要:
Apparatus including a processor configured to: receive an audio signal from a close microphone, wherein the audio signal is input in a spatial audio mixing, and the close microphone is associated with a first sound source; receive a beam-formed audio signal from a microphone array, wherein the beam-formed audio signal is a result of forming a beam of the microphone array directed from the microphone array towards the close microphone so as to enhance the audio signal; determine a time duration where no further sound source is active within the sound scene the first sound source; and determine a time difference, during the time duration, between the audio signal and the beam-formed audio signal to enable alignment of the audio signal and the beam-formed audio signal.
