Abstract: An audio system and a method of providing a faded audio experience during a transition from a first audio experience to a second audio experience, is described. The first audio experience can include playback of an audio signal spatialized using a first space impulse response that is generated by the audio system. The second audio experience includes playback of the audio signal spatialized using a second space impulse response that is received by the audio system. The audio system generates a hybrid space impulse response based on the first space impulse response and the second space impulse response. During the transition between audio experiences, the hybrid space impulse response is used to spatialize the audio signal to create the faded audio experience. Other aspects are also described and claimed.

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.

Abstract: A method includes determining a measure of a user's attention to a sound source in a spatial audio environment. Based on the measure of the user's attention to the sound source, one or more filters for decorrelating the sound source are determined. The sound source is spatially rendered, including applying the one or more filters to the sound source.
