Snippets
open a WAV file
from pydub import AudioSegment
song = AudioSegment.from_wav("never_gonna_give_you_up.wav")
...or an mp3
song = AudioSegment.from_mp3("never_gonna_give_you_up.mp3")
... or an ogg, or flv, or anything else ffmpeg supports
ogg_version = AudioSegment.from_ogg("never_gonna_give_you_up.ogg")
flv_version = AudioSegment.from_flv("never_gonna_give_you_up.flv")
mp4_version = AudioSegment.from_file("never_gonna_give_you_up.mp4", "mp4")
wma_version = AudioSegment.from_file("never_gonna_give_you_up.wma", "wma")
aac_version = AudioSegment.from_file("never_gonna_give_you_up.aiff", "aac")
Slice audio
pydub does things in miliseconds
ten_seconds = 10 * 1000
first_10_seconds = song[:10000]
last_5_seconds = song[-5000:]

Need to install ffprobe for .m4a conversion.
➡️ ffmpeg and ffprobe
convert all mp4 and flv files in a folder to mp3
import os
import glob
from pydub import AudioSegment
video_dir = '/home/johndoe/downloaded_videos/' # Path where the videos are located
extension_list = ('*.mp4', '*.flv')
os.chdir(video_dir)
for extension in extension_list:
for video in glob.glob(extension):
mp3_filename = os.path.splitext(os.path.basename(video))[0] + '.mp3'
AudioSegment.from_file(video).export(mp3_filename, format='mp3')
How to convert m4a to wav using pydub
m4a_file = '20211210_151013.m4a'
wav_filename = r"F:\20211210_151013.wav"
from pydub import AudioSegment
track = AudioSegment.from_file(m4a_file, format= 'm4a')
file_handle = track.export(wav_filename, format='wav')
