Abstract
Ray tracing is performed with sound sources and a listener position in a listening environment, to generate impulse responses associated with each of the sound sources. The impulse responses are combined to form a combined impulse response. One or more filters are determined, each corresponding to the sound sources, based on the combined impulse response and the impulse responses. Each filter serves as a correction factor that holds unique acoustic information for the sound source that the filter is associated with. The combined impulse response and the filters can be applied to one or more audio signals that contain the sound sources, resulting in audio having reverberation that is tailored to the various sound sources. Other aspects are described and claimed.
