python wav模块获取采样率 采样点声道量化位数(实例代码)

_wave_params(nchannels=1, sampwidth=2, framerate=48000, nframes=171698592, comptype='NONE', compname='not compressed')

import wave

wavFile = r"C:\Users\Lenovo\Desktop\G0001.wav"
f = wave.open(wavFile)
# 音频头 参数
params = f.getparams()
Channels = f.getnchannels()
SampleRate = f.getframerate()
bit_type = f.getsampwidth() * 8
frames = f.getnframes()
Duration = frames / float(SampleRate) # 单位为s

print("音频头参数：", params)
print("通道数(Channels)：", Channels)
print("采样率(SampleRate)：", SampleRate)
print("比特(Precision)：", bit_type)
print("采样点数(frames)：", frames)
print("帧数(Duration)：", Duration)
