中文摘要:
      讨论了一种基于LabVIEW平台,用于测试人耳对音频信号失真程度主观评价的ABX测试系统。该系统人机界面友好,提供了一个用于测试音频信号失真是否能被人耳识别的音质测试平台。该系统可用于对音频水印算法以及音频信号和语音编码等系统的性能评价。
英文摘要:
      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.
