获取音频python ffmpeg

Question

I need to get audio frequency from a flac file and save it in a variable.

I know the ffmpeg approach allowing to display info about the file:

print(os.system('ffmpeg -i '+ file_path + ' -hide_banner'))

The result looks like this:

  Duration: 00:00:11.12, start: 0.000000, bitrate: 134 kb/s
    Stream #0:0: Audio: flac, 16000 Hz, mono, s16

So the output shows the frequency, but what would be a good method to retrieve only the value of 16000 to save it in a variable?

Answer 1

Using pydub :

>>> from pydub import AudioSegment
>>> song = AudioSegment.from_mp3(file_path)
>>> song.frame_rate
48000

Answer 2

from pydub.utils import mediainfo

inf = mediainfo(file_path)
print(inf['sample_rate'])
