1) short time mean envelop
短时均值包络

To improve efficiency of the waveform similarity overlap-and-add(WSOLA) algorithm in audio signal processing at high sampling rate,this paper proposes a matching method that is progressively performed from the short time mean envelop to the signal waveform.
针对波形相似叠加算法在处理高采样率音频时效率低的缺点,提出由短时均值包络到细化波形的逐步匹配方法。
2) peak-to-mean envelope power ratio
峰值平均包络功率比

4) Envelope peak instantaneous frequency(EPIF)
包络峰值处瞬时频率
5) peak delay time of S-wave
S波包络峰值延时
1.
The peak delay time of S-wave,which is defined as the time lag from the direct S-wave onset to the maximum amplitude arrival of its envelope,is accepted to quantify the phenomenon of S-wave envelope broadening.
采用S波包络峰值延时对S波包络展宽现象进行量化。
6) envelope range value
包络幅值
补充资料：峰值音乐输出功率
英文缩写：PMPO以音乐信号瞬间能达到的峰值电压来计算的输出功率，其商业意义大于实际作用。PMPO功率可以比国际公认的有效值额定输出功率(RMS)高出3至4倍，例如早期的手提式收录机每声道RMS功率仅4、5瓦，但采用PMPO来标示，数值一下就可以增大到20W左右。
