Abstract
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.
