There is also a library for comparing WAV streams -- this would be the best for QoS measurements, and you would also be able to get the PSTN path into the test. But I didn't yet try it, as the customer was satisfied with RTP analysis: http://openpreservation.org/knowledge/blogs/2012/07/09/xcorrsound-waveform-c... https://github.com/openpreserve/scape-xcorrsound

I played a bit with the library, and it worked fairly well with a transcoded audio file: https://github.com/openpreserve/scape-xcorrsound/issues/16 I will give it some more complex tasks, like real telephony sound, going through some real network.
