1. A method of spatially rendering an audio signal, the method comprising:
determining a model of a virtual environment;
determining a spatial configuration of the virtual environment;
determining a plurality of signals associated with the spatial configuration and the model;
determining whether an energy level of the plurality of signals exceeds a predetermined threshold;
in accordance with a determination that the energy level exceeds the predetermined threshold, decoding one or more signals of the plurality of signals, the energy level corresponding to the one or more signals; and
rendering the audio signal based on the one or more decoded signals.
