摘要

提出了一种对音频信号进行高质量时间或基音修改的新方法。该方法是对拼接法的一种简单而有效的改进。由于其简单性，该算法可以在标准微处理器上实现实时运行。非正式的听力测试已经证明了该方法能够修改高质量的音频信号，而不会引入适度修改因素(高达15%)的声音伪影。

Autocorrelation method for high-quality time/pitch-scaling

A new method is described for high-quality time or pitch modifications of audio signals. The method is a simple but efficient improvement of the splice method. Thanks to its simplicity, the algorithm can be implemented to run in real-time on standard microprocessors. Informal listening tests have demonstrated the method's capability to modify high-quality audio signals without introducing audible artifacts for moderate modification factors (up to 15%).<>
