Spatial audio for interactive audio environments

A system, comprising:

• one or more speakers;
• and
• one or more processors configured to perform 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 and the one or more speakers, 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.

A non-transitory computer-readable medium storing instructions that, when executed by one or more processors, cause the one or more processors to perform 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.
