Abstract
A data processing system implements an acoustic delay detection technique for detecting and correcting inter-stream latency between two audio streams in a cloud-based computing environment. A first audio stream of game audio is sent to a controller or headset associated with the cloud-based computing environment, and a second audio steam of game audio is send to a display device associated with the cloud-based computing environment. An acoustic marker that is inaudible to human users is added to the second audio stream. A microphone associated with the controller or headset records audio content output by a speaker of the display device. The recording includes the acoustic marker. The gaming platform correlates this recording with the acoustic marker to determine a difference between the time that the controller played the audio and the time that the display device played the audio in order to determine and compensate for an inter-stream latency.
