1. A method comprising:
determining, based on a location of a sound source in a virtual environment, a first intermediate audio signal corresponding to an input audio signal;
associating the first intermediate audio signal with a first bus;
determining a distance between the location of the sound source and a location of a listener;
determining a second intermediate audio signal, the second intermediate audio signal associated with a reverberation of the input audio signal in the virtual environment;
associating the second intermediate audio signal with a second bus;
adjusting a gain of the second bus based on the distance; and
presenting, via the first bus and the second bus, an output audio signal to the listener.
