时间尺度修改（TSM）是在不改变音高的情况下加快或减慢音频信号的播放速度的任务。在数字音乐制作中，TSM已经成为一个不可缺少的工具，它现在被集成在广泛的音乐制作软件中。音乐信号是多种多样的——它们包括谐波、打击乐和瞬态成分等。由于这种广泛的声学和音乐特性，没有一种TSM方法可以同样地处理各种音频信号。我们的主要目标是促进对TSM过程的功能和限制的更好理解。为此，我们回顾了基本的TSM方法，讨论了典型的挑战，并指出了结合不同策略的潜在解决方案。特别地，我们讨论了一种融合方法，该方法涉及到谐波冲击分离的最新技术以及时域和频域TSM程序。
Time-scale modification (TSM) is the task of speeding up or slowing down an audio signal’s playback speed without changing its pitch. In digital music production, TSM has become an indispensable tool, which is nowadays integrated in a wide range of music production software. Music signals are diverse—they comprise harmonic, percussive, and transient components, among others. Because of this wide range of acoustic and musical characteristics, there is no single TSM method that can cope with all kinds of audio signals equally well. Our main objective is to foster a better understanding of the capabilities and limitations of TSM procedures. To this end, we review fundamental TSM methods, discuss typical challenges, and indicate potential solutions that combine different strategies. In particular, we discuss a fusion approach that involves recent techniques for harmonic-percussive separation along with time-domain and frequency-domain TSM procedures.
