An ABX audio assessment system based on LabVIEW

This paper describes a computer-aided measurement system developed on a LabVIEW platform for subjective audio quality assessment. The assessment is based on the ABX method for sound quality comparison of audio signal pairs. With a user-friendly interface, the system provides a useful tool in the evaluation of watermarking algorithms that embed secret data in Hi-Fi music for copyright identification without causing audible distortion. The system is also applicable to the evaluate of audio/speech coding techniques.
