A Method for Quantitative Evaluation of Audio Quality Over Packet Networks and Its Comparison With Existing Techniques
Samir A. Elsagheer Mohamed, Martı́n Varela, Gerardo Rubino, Martn Varela · 2004
We have recently proposed a novel, non--intrusive, real-- time approach to measuring the quality of an audio (or speech) stream transmitted over a packet network. The proposed approach takes into account the diversity of the factors which affect audio quality, including encoding parameters and network impairments. The goal of this method is to overcome the limitations of the quality assessment techniques currently available in the literature, such as the low correlation with subjective measurements, or the need to access the original signal, which precludes real--time applications.
