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.
