Disclosed are systems, methods, and non-transitory computer-readable storage media for altering and combining real and simulated audio streams. For example, a system can determine a location of a first unmanned aerial vehicle (UAV). The system can then determine a location of an object and can receive an audio stream associated with the object. The system can then determine a distance between the location of the first UAV and the location of the object. The system can adjust the audio stream volume according to the distance. The system can then send the audio stream to a listener.
