摘要

当前的时间尺度修改算法将所有频率按相同的量进行缩放。本文提出了一种对任意频率区域进行时间标度的有效方法和实现，称为频率相关时间标度修正。这是通过在使用传统频域时间标度方法之前创建复合频谱帧来实现的。对3个文件进行了不同的处理，得到了测试结果。提供了MATLAB实现的链接和描述。可用性:MATLAB软件实现可以在Github上找到github.com/zygurt/TSM。

Frequency Dependent Time-Scale Modification

Current Time-Scale Modification algorithms scale all frequencies by the same amount. This paper presents an efficient method and implementation for time scaling of arbitrary frequency regions, called Frequency Dependent Time-Scale Modification. This is achieved by creating a composite frequency spectrum frame before using traditional frequency domain time-scaling methods. Testing was undertaken with results presented from varied processing of 3 files. Links to and description of a MATLAB implementation are provided. Availability: A MATLAB software implementation can be found on Github at github.com/zygurt/TSM.
