Description - Audio Codecs Quality Analyzer



Voice coders (vocoders) quality is usually measured according to a mean subjective estimation - MOS (Mean Opinion Score). MOS is usually calculated as expert estimations of a set of speech signals played by different phones. Each expert gives his score: 1 = bad, 2 = poor, 3 = clear, 4 = good, 5 = excellent. Mean value of the obtained results is taken afterwards. CISCO Systems (www.cisco.com) gives test results for different codecs according to the clearest speech signal. Further down one can find CISCO test results compared to our automated audio codecs quality tests algorithms (ALG1, ALG2):
