Pydub-如何在不更改播放速度的情况下更改帧速率 [英] Pydub - How to change frame rate without changing playback speed

问题描述

我有几个音频文件，是使用AudioSegment在Pydub中打开的.

I have a couple audio files that I open in Pydub with AudioSegment.

我想将音频质量从帧速率22050降低到16000 Hz. (一个频道文件)

I want to decrease the audio quality from frame rate 22050 to 16000 Hz. (One channel files)

如果仅更改AudioSegment的帧频，我得到的就是在较低速度下播放的完全相同的波形.好吧，很公平.

If I simply change the frame rate of AudioSegment, what I get is the exact same wave played in slower speed. Well, fair enough.

但是我如何真正改变波形以适应较低质量，相同速度的播放?

But how do I actually change the waves to fit a lower quality, same speed playback?

(我只能想到手动插值，但我不想遇到麻烦)

(Manual interpolation is the only thing I can think of, but I don't want to get into that trouble)

推荐答案

您可以使用:

sound = AudioSegment.from_file(…)
sound = sound.set_frame_rate(16000)
