Question

mp3转pcm格式python3的文档哪位同学有

Answer 1

参考 Python: How to decode a mp3 chunk into PCM samples?

Answer 2

安装ffmpy，使用ffmpeg转化(https://ffmpeg.org/download.html#build-windows)

将下载的ffmpeg.exe放在项目下面的scripts目录下

from ffmpy import FFmpeg

#将mp3转化没pcm
ff = FFmpeg(inputs={r'd:\test\venv\Scripts\test.mp3':"-y"},
           outputs={r'd:\test\venv\Scripts\test.pcm':"-acodec pcm_s16le -f s16le -ac 2 -ar 16000"})

print(ff.cmd)
ff.run()

#将pcm转化为mp3
ff1 = FFmpeg(inputs={r'd:\test\venv\Scripts\test.pcm':"-y -f s16be -ac 2 -ar 16000 -acodec pcm_s16le"},
           outputs={r'd:\test\venv\Scripts\test1.mp3':None})

print(ff1.cmd)
ff1.run()
