问题
I have a couple audio files that I open in Pydub with AudioSegment.
I want to decrease the audio quality from frame rate 22050 to 16000 Hz. (One channel files)
If I simply change the frame rate of AudioSegment, what I get is the exact same wave played in slower speed. Well, fair enough.
But how do I actually change the waves to fit a lower quality, same speed playback?
(Manual interpolation is the only thing I can think of, but I don't want to get into that trouble)
回答1:
You can use:
sound = AudioSegment.from_file(…)
sound = sound.set_frame_rate(16000)
