Python Object List Consolidation for Pydub Module
I am trying to combine a list of wav files together into one audio file. So far, this is what I have. I can't wrap my head around how to sum the objects though, since each one is an object.
import glob, os
from pydub import AudioSegment
wavfiles = []
for file in glob.glob('*.WAV'):
wavfiles.append(file)
outfile = "sounds.wav"
pydubobjects = []
for file in wavfiles:
pydubobjects.append(AudioSegment.from_wav(file))
combined_sounds = sum(pydubobjects) #this is what doesn't work of course
# it should be like so
# combined_sounds = sound1 + sound2 + sound 3
# with each soundX being a pydub object
combined_sounds.export(outfile, format='wav')

The function sum
fails because its default value is 0 and you cannot add AudioSegment
an integer either .
You just need to add the initial value like so:
combined_sounds = sum(pydubobjects, AudioSegment.empty())
Also, you don't need separate loops if you just want to concatenate files (and don't need intermediate lists of filenames or objects AudioSegment
):
import glob
from pydub import AudioSegment
combined_sound = AudioSegment.empty()
for filename in glob.glob('*.wav'):
combined_sound += AudioSegment.from_wav(filename)
outfile = "sounds.wav"
combined_sound.export(outfile, format='wav')
