  • Fitting background ambiance to sound objects
    Patent number: 10425760
    Abstract: Embodiments of these teachings concern integrating a sound object such as an audio object recorded by, e.g., a lavalier microphone to a spatial audio signal. First the sound object is obtained and then a direction and an active duration of the sound object is determined. The spatial audio signal is compiled from audio signals of multiple microphones and could be pre-recorded and obtained after the fact. Then, using the determined direction, the sound object is integrated with the spatial audio signal over the active duration. If there are further moving sound sources to integrate the same procedure is followed for them all individually. One technique specifically shown herein to find the optimized direction and starting time is steered response power with phase transform weighting.

  • Audio Object Adjustment For Phase Compensation In 6 Degrees Of Freedom Audio
    Publication number: 20180359592
    Abstract: Phase effect interference is determined at a listening location between signals from at least two audio objects; and a modified position is computed for at least one of the audio objects such that the determined phase effect interference at the listening location is altered as a result of the modified position. For each audio object for which the position is modified at least phase of at least one frequency component of the respective signal is adjusted in correspondence with the modified position so as to eliminate the determined phase effect interference. The signals from the at least two audio objects are formed after this adjusting; and then the formed signals are provided to a sound system comprising multiple audio transducers so as to render the formed signals at the listening position where the phase effect interference is eliminated during rendering.
