Python 将 wav 转换为 mp3

Question

I've looked at pymedia (discontinued), pyglet(great but no converter in there) and audiotools(command line cd ripping), and none seem suitable.

In Python 2.7 , how do you do

convert(wavFileLocation, 'mp3')

If there is no python way, how would you do it in a manner which python can invoke? (eg Call a Cross platform command line tool... if exists return (name, pythonCodeForInvocation) )

Answer 1

I wrote a python library, pydub , that essentially does what Corey's Answer suggests, though it uses ffmpeg in to do the conversions in order to support more formats.

from pydub import AudioSegment

AudioSegment.from_wav("/input/file.wav").export("/output/file.mp3", format="mp3")

Answer 2

using lame (command line), you can encode wav to mp3 like this:

$ lame --preset insane /path/to/file.wav

which would create:

file.wav.mp3

in Python, you could use subprocess to call it:

wav = 'myfile.wav'
cmd = 'lame --preset insane %s' % wav
subprocess.call(cmd, shell=True)

Answer 3

You must go for pydub, it is a great module for operations related with audio files.

NOTE. Do remember to install ffmpeg before you use pydub.

For help regarding installation of ffmpeg , you can use this link .

Then to install pydub just open your command prompt and type

pip install pydub

Then to convert any file from wav to mp3 just use pydub as

import pydub
sound = pydub.AudioSegment.from_wav("D:/example/apple.wav")
sound.export("D:/example/apple.mp3", format="mp3")

Answer 4

will you can just rename the file extension , i think os library will help you any way i will give you example :

yourfile.wav ==>> yourfile.mp3 or any type that is for audio and video file

for me it's worked !!
