| Abstract | A method and apparatus are disclosed to recreate directional cues and in a conventional beamformed monophonic audio signal. In an example embodiment, the apparatus captures sound in an environment via the microphone array which includes a left reference and a right reference microphone. A monophonic audio signal is generated using conventional beamforming methods. A conventional monophonic beamformed signal lacks directional cues which may be useful for multiple output channels. By applying the phase offset data of the audio signals at the left and right reference microphones, directional cues may be created for audio signals for the left and right output channels respectively. |
