Dynamic Latency Estimation for Audio Streams
Systems and methods for packet dynamic latency estimation for audio streams may include, for example, capturing a first audio signal using a microphone of a computing device; receiving a second audio signal at the computing device via wireless communications from an access point; determining a set o...

| description | Systems and methods for packet dynamic latency estimation for audio streams may include, for example, capturing a first audio signal using a microphone of a computing device; receiving a second audio signal at the computing device via wireless communications from an access point; determining a set of estimates of a delay of the first audio signal relative to the second audio signal based on a cross-correlation at respective analysis steps within the first audio signal and the second audio signal; determining an average delay and a confidence interval for the set of estimates of the delay; comparing the confidence interval to a threshold duration; and, responsive to the confidence interval being less than the threshold duration, playing, using a speaker controlled by the computing device, an audio signal received from the access point with an added delay determined based on the average delay. |
