Avaliação objetiva de qualidade de sinais de audio e voz

Jayme Garcia Arnal Barbedo-2004-01-01

TL;DRAbstract

This work deals with the problem of objective quality assessment of audio and speech signals. The theoretic foundation regarding the mathematical modeling of human ear, audio signal codification and subjective and objective assessment, is presented. Two new methods for objective assessment, named MOQA and AOSV, are proposed. The validation of such methods is performed using a detailed statistical analysis and comparing the results with the most important strategies currently in use. Finally, a critical analysis of the advances achieved during the research is presented, along with the proposal of some directives for future studies. viii 8.3.1.10. Modelagem do Efeito de Assimetria . . . . . .
