Abstract: In a particular aspect, a multimedia device includes one or more sensors configured to generate first sensor data and second sensor data. The first sensor data is indicative of a first position at a first time and the second sensor data is indicative of a second position at a second time. The multimedia device further includes a processor coupled to the one or more sensors. The processor is configured to generate a first version of a spatialized audio signal, determine a cumulative value based on an offset, the first position, and the second position, and generate a second version of the spatialized audio signal based on the cumulative value.

Abstract: In a particular aspect, a multimedia device is configured to compensate for navigational movement within a visual environment. The multimedia device includes a processor configured to generate a first version of a spatialized audio signal of a sound field in a first audio frame based on a first position within a visual environment. The processor is configured to generate a second version of the spatialized audio signal of the sound field in a second audio frame based on compensating for the speed of movement of the multimedia device that indicates the first position within the visual environment changed to a second position within the visual environment, being different than the speed of movement in changing from a first location of the sound field to a second location of the sound field.
