A cloud-based video/audio conferencing system and method performs locale based aggregation of a full duplex media stream to organize multiple connections to a conference call that originate from the same physical location or a shared locale. The cloud-based video/audio conferencing system performs synchronization of the microphone and speaker audio signals of the same-locale connections. In this manner, a conference call may be held with multiple user devices making connections from the same physical location. User experience is enhanced by allowing each user in the same location to use his/her own individual devices to connect to the same conference call.

Dynamic locale based aggregation of full duplex media streams

A latency compensating adaptive jitter buffer method is implemented. In response to a queuing delay event being detected, the size of the jitter buffer is temporarily increased to receive all incoming audio packets up to a certain refill level. The method then produces audio playback using accelerated playback to reduce the jitter buffer size back to the nominal size.

Adaptive audio stream with latency compensation cross reference to other applications

A latency compensating adaptive jitter buffer method is implemented in an audio client running on a user device or in an audio server to adaptively adjust the size of a jitter buffer to optimize latency while minimizing packet loss during audio signal transmission. In some embodiments, the jitter buffer is kept to a nominal size for low latency. In response to a queuing delay event being detected, audio production is temporarily stopped and the size of the jitter buffer is temporarily increased to receive all incoming audio packets up to a certain refill level. The method then resumes audio production using accelerated playback to reduce the jitter buffer size back to the nominal size.
