20210400416 | SYNTHESIZING AUDIO OF A VENUE - Disclosed herein are system, method, and computer program product embodiments for replicating a remote venue in a local venue. An embodiment operates by receiving original audio. Thereafter, the original stream of audio is modified to produce modified audio based on an audio profile unique to a remote venue smaller than the local venue. The audio profile comprises a virtual representation of the remote venue including (i) a virtual audio source corresponding to the local venue's audio source and configured to produce the original audio and (ii) a virtual reverberation point corresponding to a real-world location in the remote venue and the portion of the local venue. As such, the modified audio is determined based on receipt of the original audio from the reverberation point. Thus, after correlating the modified audio to the local venue's audio source, the modified audio is provided by the audio source to the portion of the local venue. | 2021-12-23 |
20210400417 | SPATIALIZED AUDIO RELATIVE TO A PERIPHERAL DEVICE - An audio system, method, and computer program product which includes a wearable audio device and a mobile peripheral device. Each device is capable of determining its respective absolute or relative position and orientation. Once the relative positions and orientations between the devices are known, virtual sound sources are generated at fixed positions and orientations relative to the peripheral device such that any change in position and/or orientation of the peripheral device produces a proportional change in the position and/or orientation of the virtual sound sources. Additionally, first order and second order reflected audio paths may be simulated for each virtual sound source to increase the realism of the simulated sources. Each sound path can be produced by modifying the original audio signal using head-related transfer functions (HRTFs) to simulate audio as though it were perceived by the user's left and right ears as coming from each virtual sound source. | 2021-12-23 |
