对wave文件进行读取，并提取短时平均能量，过零率，短时平均幅值值，音频中每一帧的最大值，最小值-right wave to read documents and extract short-term average energy, the zero-rate, short-term value of the average amplitude, Audio each frame of the maximum, minimum

语音信号的短时分析，主要包括：分帧、短时能量、短时平均幅度、短时过零率、短时自相关函数、短时幅度差、倒谱、复倒谱、lpc系数、lpc谱估计等-Short-time speech signal analysis, mainly including: sub-frame, short-time energy, short-term average, short-time zero-crossing rate, short-time auto-correlation function, short-t

读入语音文件bluesky1.wav（内容为“蓝天，白云，碧绿的大海”）中的数据，进行分帧处理，然后计算其短时平均过零率。(Read the data from the voice file bluesky 1. wav (blue sky, white clouds, green sea), frame it, and calculate its short-term average zero-crossing rate.)
