python 声音处理 AudioSegment.from_fi

经历好几个小时的折腾

from pydub.audio_segmentimport AudioSegment

from scipy.ioimport wavfile

from python_speech_features.baseimport mfcc

import pandas

import  sys

song = AudioSegment.from_file('D:/demo/xihuani.MP3',format='MP3')

print(song)

错误

上面的错误是少安装了 ffmpeg 但是你用pip install ffmpeg 安装后还是一样的错误

然后呢 你需要自己去官网下载 。exe的然后再去代码调用ffmpeg

最后

from pydub.audio_segmentimport AudioSegment

from scipy.ioimport wavfile

from python_speech_features.baseimport mfcc

import pandas

import  sys

AudioSegment.converter ='D:\\ffmpeg\\bin\\ffmpeg.exe'

song = AudioSegment.from_file('D:/demo/xihuani.MP3',format='MP3')

print(song)
