Abstract: Systems, methods, and computer media for adjusting acoustics in real time are provided herein. An acoustic adjustment system can include a processor, a memory, a voxelizer, and a pathing analyzer. The voxelizer can be configured to generate a voxel-based representation of a three-dimensional (3D) interactive media environment. The voxel-based representation includes a number of individual voxels that together represent the environment. The voxelizer can also be configured to identify a plurality of blocked voxels that intersect visual elements of the 3D interactive media environment. The pathing analyzer can be configured to determine, for the clear voxels, audio path information representing a path of clear voxels between the voxel and the location of the listener. The audio path information can be used to adjust sounds emitted by sound emitters in the media environment to realistically reflect the distances the sound travels to reach the listener.

Abstract: The subject disclosure is directed towards calibrating sound pressure levels of speakers to determine desired attenuation data for use in later playback. A user may be guided to a calibration location to place a microphone, and each speaker is calibrated to output a desired sound pressure level in its current acoustic environment based upon the attenuation data learned during calibration. During playback, the attenuation data is used. Also described is testing the setup of the speakers, and dynamically adjusting the attenuation data in real time based upon tracking the listener's current location.

Abstract: The subject disclosure is directed towards a pre-cognitive interactive music system that dynamically generates and adjusts music based on a user's interactions with a videogame or other interactive system. When a user is predicted as getting close to an upcoming event, audio clips are dynamically selected (e.g., via metric modulation) based upon an estimated time to reach the event. The audio clips are stitched together and played as prelap music as the user approaches the event, and the clips may be varied if the estimated time changes due to user interaction. Drawdown music is similarly selected as the user completes or moves away from an event. Also described is the changing of the playing rate to adjust the music, and the use of harmonic modulation to change the music's key over time to increase or lower perceived suspense as the user approaches the event or moves away from it, respectively.
