Abstract
Methods, systems, and computer readable media for utilizing ray-parameterized reverberation filters to facilitate interactive sound rendering are disclosed. According to one method, the method includes generating a sound propagation impulse response characterized by a plurality of predefined number of frequency bands and estimating a plurality of reverberation parameters for each of the predefined number of frequency bands of the impulse response. The method further includes utilizing the reverberation parameters to parameterize a plurality of reverberation filters in an artificial reverberator, rendering an audio output in a spherical harmonic (SH) domain that results from a mixing of a source audio and a reverberation signal that is produced from the artificial reverberator, and performing spatialization processing on the audio output.
