1. 摘要

The spectral analysis of signals is currently either dominated by the speed–accuracy trade-off or ignores a signal’s often nonstationary character.
翻译： 信号的频谱分析是目前由计算速度-准确率的权衡法则主宰或忽略了信号的非平稳特征。
完善版本： 信号的频谱分析通常是由计算效率、内存消耗与准确率的权衡或者部分忽略了信号的非平稳特性。

Here we introduce an open-source algorithm to calculate the fast continuous wav
