Abstract
A method for scaling audio content using reverberant energy for the placement of virtual audio sources in an artificial reality experience. The method comprises obtaining a set of critical distance parameters. The set of critical distance parameters include at least a reverberation time of a local area and a geometry of the local area. The method further comprises determining a critical distance for the local area based on the set of critical distance parameters and scaling an amplitude of audio content based in part on the critical distance and a distance between a target location in the local area and an artificial reality headset in the local area. The method further comprises presenting the audio content by the headset in accordance with the scaled amplitude.
