Abstract: An apparatus (101) for enabling reproduction of spatial audio signals. The apparatus comprises means for obtaining (401) audio signals (501) comprising one or more channels and obtaining (403) spatial metadata (503) relating to the audio signals (501). The spatial metadata (503) comprises information that indicates how to spatially reproduce the audio signals. The apparatus also comprises means for obtaining (405) information relating to a field of view of video (505) wherein the video is for display on a display (205) of a rendering device (201) and wherein the video is associated with the audio signals (501). The apparatus also comprises means for aligning (407) spatial reproduction of the audio signals based, at least in part, on the obtained spatial metadata (503), with objects (309A, 309B) in the video according to the obtained information relating to the field of view of video; and enabling (409) reproduction of the audio signals based on the aligning (407).
