1. A method comprising:
determining, based on a location of a sound source and further based on an acoustic property of a virtual environment, an intermediate audio signal, the intermediate audio signal corresponding to a reflection of an input audio signal by a surface of the virtual environment, wherein:
said determining the intermediate audio signal comprises encoding the input audio signal based on the location of the sound source, and
the intermediate audio signal is associated with a first plurality of channels;
associating the intermediate audio signal with a bus, wherein the bus is associated with the first plurality of channels; and
presenting, via the bus, an output audio signal to a listener, wherein:
the output audio signal is determined via decoding the intermediate audio signal to produce a decoded intermediate audio signal, and
the decoded intermediate audio signal is associated with a second plurality of channels, different from the first plurality of channels.
