UC San Diego created a trumpet that not only detects the exact pitch being played, but can bend that pitch in real time to hit the proper note-a sort of auto-tune for the brass section.

加州大学圣地亚哥分校小队发明了一种小号，不仅可以检测小号演奏时的精确音高，还能实时将音高对应至合适的音符——类似于一种铜管乐器的自动调音装置。

A pitch tracking algorithm was developed based on the normalized sum of the magnitude difference square function (SMDSF) for accurately estimating speech pitch at any sample rate in real time.

为了在任意采样率下都可以高效、准确地进行基音周期提取，提出基于归一化幅度差平方和函数的基音周期提取算法。
