Abstract
A device may include a plurality of microphones, and a processor configured to extract a sound and a sound field from microphone signals of the plurality of microphones. The sound may be treated as near-field sound and the sound field may be treated as far-field sound. The device may adjust a strength of the sound based on a strength of the sound field and apply near-field head related transfer functions (HRTFs) to the sound. The device may apply far-field HRTFs to the sound field. The device may combine the near-field applied sound with the far-field applied sound field to generate spatial audio for playback through a plurality of speakers.
