It evaluates the efficiency of the EPTMA clock skew detection algorithm applied to real-time audio streaming over a local network. The presented results include real world apparent deviations of audio card clocks and acuracy of the skew detection. It appears that EPMTA is very suitable to measure clocks deviation in the context of audio transport. Finally, a simple method to compensate for the clock skew is presented, mainly to evaluate a complete solution for audio streaming.}, keywords = {audio, clock, network, real-time, skew}, pubstate = {published}, tppubtype = {techreport} } This paper is the continuation of a previous work done on clock skew compensation over a high latency network.
