Creating an empty AudioSegment File in Python (pydub)

Question

Beginner here. I'm trying to loop through a list of paths to mp3 files and merge all the mp3s:

combined_sounds = AudioSegment.from_mp3('./00.mp3')

for file in files:
  sound = AudioSegment.from_mp3(file)
  combined_sounds= combined_sounds + sound;

# ....

I need to define combined_sounds before going through the list - but I'd like to not put anything into it before going through the loop. Right now my little hack is to use an empty mp3 file 00.mp3 , but this isn't the nicest solution. How would I accomplish this?

I tried combined_sounds = '' and combined_sounds = None but both get me errors when I then enter the loop and try to turn it into an AudioSegment. Can I create an empty AudioSegment before the loop maybe?

Answer 1

You can use the empty() function in AudioSegment to create a blank segment:

combined_sounds = AudioSegment.empty()

for file in files:
   sound = AudioSegment.from_mp3(file)
   combined_sounds += sound
