![]() ![]() ![]() Personal Listening Test of MP3/Opus/AAC at 96kbps by Kamedo2 (1 listener)ĭraft. The research log below is updated live as the work goes on.Ĭase #1. Such measurements, based on statistical difference testing, can be translated into quality scores directly and will be valid for both analog and digital domains. Objective measurements with high correlation to subjective scores.Also results of an already finished listening test could be reused many times by adding new contenders afterwards and computing their quality scores analytically. A listening test conducted for several contenders could provide quality scores for many more contenders with foreknown accuracy. If such dependency is proved then reliable audio quality assessment will become easier and cheaper by means of: For the purpose several listening test cases (the more, the better) should be examined comparing levels of waveform degradation with subjective quality scores. This research is aimed to explore such relationship and its limitations. Preliminary research at SoundExpert shows that there is high probability that relationship between waveform degradation of an audio material and its auditory perception does exist. ![]()
