matlab环境下，实现将wav格式的音频文件进行分帧，求能量，过零率,matlab environment, to achieve wav format audio files framing, and energy, zero-crossing rate

基于短时能量的基音短点检测，有基于短时能量的计算方法、短时过零率，有matlab程序，同事对应word讲解，算法原理图，和算法详细介绍。-Short pitch detection based on short-term energy, based on the calculation method of the short-time energy, short-time zero-crossing rate, matlab program, colleagues corresponding w

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.)
