I'm load testing an asterisk application, and I'd like to determine the audio quality automatically. I'm already doing DTMF tests, but I'm looking for something a little fuzzier I think.
My initial knee-jerk reaction is to record the audio, and then apply some sort of algorithm to it that will provide me with a few metrics to compare with the original recording. Some very preliminary research has turned up two standards, "Perceptual Analysis/Measurement System" (PAMS), and "Perceptual Speech Quality Measure" (PSQM) -- does anyone have any insights into what is behind these standards, or whether they're worth researching?
