Claim One:
1. A method for generating a video with corresponding audio, comprising: receiving a spherical video; receiving a plurality of audio channels representing audio captured concurrently with the spherical video, each of the plurality of audio channels comprising directional audio corresponding to respective different directions; defining respective spatial sub-regions to subdivide the frame of the spherical video; mapping each of the plurality of audio channels to different spatial sub-regions of the spherical video such that each sub-region is associated with at least one audio channel; for each of a plurality of frames of the spherical video, extracting a sub-frame having a reduced field of view relative to a field of view of the spherical video; for each of the sub-frames, by a processor, determining one or more of the spatial sub-regions overlapping the sub-frame; determining a composite audio channel, the composite audio channel being a combination of the audio channels mapped to the one or more of the spatial sub-regions overlapping the sub-frame; generating a portion of an audio stream from the composite audio channel; and outputting the generated video and the audio stream.
