Title
(EN) METHODS AND SYSTEMS FOR RECORDING MIXED AUDIO SIGNAL AND REPRODUCING DIRECTIONAL AUDIO
Abstract
(EN)

Methods and systems are provided for recording mixed audio signal and reproducing directional audio. A method includes receiving a mixed audio signal via plurality of microphones; determining an audio parameter associated with the mixed audio signal received at each of the plurality of microphones; determining active audio sources and a number of the active audio sources from the mixed audio signal; determining direction and positional information of each of the active audio source; dynamically selecting a set of microphones from the plurality of microphones based on at least one of the number of the active audio sources, the direction of each of the active audio sources, the positional information of each of the active audio sources, the audio parameter, or a predefined condition; and recording, based on the selected set of microphones, the mixed audio signal for reproducing directional audio.
