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.
