摘要： A dual source spatialized audio system includes a general audio system and a personal audio system. The general system includes a general audio processor and general speakers to produce general sound. The personal system includes a frame to be worn on a head of a user and a plurality of personal speakers attached to the frame. The personal system also includes a head pose sensor to collect head pose data of the user. The personal system further includes a head pose processor to determine a head pose of the user from the head pose data. Moreover, the personal system includes a personal audio processor to generate personal audio data based on the head pose of the user. The personal speakers generate personal sound corresponding to the personal audio data. The personal processor receives timing information/metadata from the general audio processor to synchronize the personal sound with the general sound.

摘要： Systems, devices, and methods for capturing audio which can be used in applications such as virtual reality, augmented reality, and mixed reality systems. Some systems can include a plurality of distributed monitoring devices. Each monitoring device can include a microphone and a location tracking unit. The monitoring devices can capture audio signals in an environment, as well as location tracking signals which respectively indicate the locations of the monitoring devices over time during capture of the audio signals. The system can also include a processor to receive the audio signals and the location tracking signals. The processor can determine one or more acoustic properties of the environment based on the audio signals and the location tracking signals.

摘要： Systems and methods for capturing audio which can be used in applications such as virtual reality, augmented reality, and mixed reality systems. Some systems may include a plurality of distributed monitoring devices in an environment, each having a microphone and a location tracking unit. The system can capture audio signals while also capturing location tracking signals which indicate the locations of the monitoring devices over time during capture of the audio signals. The system can generate a representation of at least a portion of a sound wave field in the environment based on the audio signals and the location tracking signals. The system may also determine one or more acoustic properties of the environment based on the audio signals and the location tracking signals.
