Python读取WAV文件的几种方式整理

1）scipy

from scipy.io import wavfile
import numpy as np

sample_rate, sig = wavfile.read('new.wav')
print("采样率: %d" % sample_rate)
print(sig)

if sig.dtype == np.int16:
    print("PCM16位整形")
if sig.dtype == np.float32:
    print("PCM32位浮点")

输出如下:

采样率: 16000
[-1466  -733  -733 ...  2199  1832  1466]
PCM16位整形

2）pysoundfile

import soundfile as sf

sig, sample_rate = sf.read('new.wav')

print("采样率：%d" % sample_rate)
print(sig)

输出如下：

采样率：16000
[-0.04473877 -0.02236938 -0.02236938 ...  0.06710815  0.0559082
  0.04473877]

3）wave

不推荐此库

WAV格可以用16位整形或者32
