我如何使用python混合音频文件？ [英] How do I mix audio files using python?

问题描述

我愿做基本的音频混合蟒蛇

I would like to do basic audio mixing in python.

要举个例子：我想需要两个mp3文件，并添加在一起，并返回的MP3文件。又如：我想举一个MP3文件的前十秒钟，它添加到另一个MP3文件的开头

To give an example: I would like to take two mp3 files and add them together and return one mp3 file. Another example: I would like to take the first ten seconds of one mp3 file and add it to the beginning of another mp3 file.

什么是完成这些任务的最佳方式？我想用建于​​像audioop Python函数，但找不到任何好的教程或样品code那里为使用内置的功能。

What is the best way to accomplish these tasks? I would like to use built in python functions like audioop but can not find any good tutorials or sample code out there for using the built in functions.

我经历的文档，但我pretty混乱，无法弄清楚如何做这样的事情。我甚至不能确定，像MP3的蟒蛇库。大部分我看过的东西似乎是指WAV文件。所以，如果是这样的话，我想跟进的问题是有没有一个简单的方法，以一个MP3转换为操纵WAV和回来？

I am going through the docs but I am pretty confused and cannot figure out how to do things like this. I am not even sure that the python libraries like mp3's. Most of the stuff I have looked at seem to refer to WAV files. So, if this is the case, I guess a follow up question would be is there an easy way to convert an mp3 to a WAV for manipulation and back again?

推荐答案

您可以轻松地做到这一点pretty使用 pydub ：

You can do this pretty easily using pydub:

from pydub import AudioSegment

sound1 = AudioSegment.from_mp3("/path/to/file1.mp3")
sound2 = AudioSegment.from_mp3("/path/to/file1.mp3")

# mix sound2 with sound1, starting at 5000ms into sound1)
output = sound1.overlay(sound2, position=5000)

# save the result
output.export("mixed_sounds.mp3", format="mp3")
