Sammanfattning: The report describes a quality measurement for audio, both the theoretical background and implementation. It begins by describing the unlicensed methods the implementation is based on, Segmental SNR, Frequency Weighted Segmental SNR, Log-Likelihood Ratio, Cepstral Distance and Weighted Slope Spectral distance, and the commercial methods used as reference, PEAQ and PESQ. It also mentions the problems present in wireless transfer and the concept of sound quality assessment. It concludes by describing the suggested analysis method and implemented software together with the results when compared to PEAQ and PESQ.
