    • A method for measuring perceptual quality of voice signals, audio signals, audio-video signals, and multimedia signals in communication equipment in an operational embodiment communicates a processed test signal via a network from a first device to a second device. The processed test signal is then received by an equipment under test, which further processes the processed test signal to recover a representation of the test signal. The recovered test signal is then objectively analyzed to determine a measure of perceptual quality by comparing the recovered test signal to a pre-stored representation of the test signal. A quality measurement unit that conveniently attaches to equipment under test identifies and evaluates quality of recovered test signals communicated from a remote device, or a test signal communicated by the equipment under test. In the latter case, the quality measurement unit communicates with both the equipment under test and with the network, so that the quality measurement unit itself receives a representation of the communicated test signal by the equipment under test.
