Python:将WAV文件写入numpy浮点数组 [英] Python: write a wav file into numpy float array

问题描述

ifile = wave.open("input.wav")

我现在如何将该文件写入numpy浮点数组?

how can I write this file into a numpy float array now?

推荐答案

>>> from scipy.io.wavfile import read
>>> a = read("adios.wav")
>>> numpy.array(a[1],dtype=float)
array([ 128.,  128.,  128., ...,  128.,  128.,  128.])

通常是字节，然后是整数...这里我们只是将其转换为浮点型

typically it would be bytes which are then ints... here we just convert it to float type
