1. A method comprising:
obtaining a virtual space that includes a virtual speaker distribution of a plurality of virtual speakers within the virtual space, the virtual space representing a physical environment;
obtaining an audio file that includes audio corresponding to an audio object of an audio scene;
generating one or more audio signals based on the virtual speaker distribution and the audio file, the generating being such that presentation of the one or more audio signals by speakers within the physical environment represented by the virtual speakers produces the audio in a manner that simulates the audio object in the physical environment;
mapping each respective virtual speaker location to a respective point source location in an audio localization environment that corresponds to the virtual space, the mapping including providing point source data to an audio localization system such that a distribution of point sources in the audio localization environment matches the virtual speaker distribution within the virtual space; and
providing the one or more audio signals to the audio localization system according to the mapping of the virtual speakers to their respective point sources, the audio localization system being configured to, based on the one or more audio signals corresponding to respective point sources according to the mapping, synthesize a binaural sound for playback by a set of stereo speakers such that the audio is simulated as being presented by speakers within the physical environment that are represented by the virtual speakers, the providing the one or more audio signals according to the mapping including providing a particular audio signal to a particular point source based on the particular audio signal being designated for a particular virtual speaker that is mapped to the particular point source.
