如何在pydub中获得相同的输入和输出文件比特率?

问题描述

我已经使用pydub输出文件(将文件切成较短的文件)，一切都很好，但是比特率已从256k更改为124k(为什么我会得到这个数字而不是128k?).我知道AudioSegment有一个参数来设置比特率，但是我只想使用相同的比特率，而不是每次手动设置.有什么办法解决这个问题?

I've use pydub to output a file(chop the file into shorter one), everything is great, but the bitrate has changed from 256k to 124k(why I will get this number instead 128k?). I know that AudioSegment has an argument to set bitrate, but I just want the same bitrate instead manually set every time. Any way to fix this issue?

推荐答案

这主要与ffmpeg/avlib有关，但是您可以将标志传递给 AudioSegment().export()方法指定所需的比特率:

This has mainly to do with ffmpeg/avlib, but you can pass a flag to the AudioSegment().export() method to specify the bitrate you'd like:

from pydub import AudioSegment
from pydub.utils import mediainfo

source_file = "/path/to/sound.mp3"

original_bitrate = mediainfo(source_file)['bit_rate']
sound = AudioSegment.from_mp3(source_file)

sound.export("/path/to/output.mp3", format="mp3", bitrate=original_bitrate)
