Pydub concatenate mp3 in a directory

Question

I would like to concatenate all .mp3s in one directory with pydub. The files are numbered consecutively file0.mp3, file1.mp3 etc.

this code from the example code:

playlist_songs = [AudioSegment.from_mp3(mp3_file) for mp3_file in glob("*.mp3")] 

gives me all files and now I would like to concatenate, like in pseudocode:

for i in playlist_songs:
    append i to finalfile

Is there a way to achieve this or am I approaching it wrong ?

Thanks for the help !

Answer 1

you can start with an empty sound like so:

combined = AudioSegment.empty()
for song in playlist_songs:
    combined += song

combined.export("/path/to/output.mp3", format="mp3")

or if you'd like to get a little fancy and use 5 second crossfades you'll have to pop the first song off the list

combined = playlist_songs[0]

for song in playlist_songs[1:]:
    combined = combined.append(song, crossfade=5000)

combined.export("/path/to/output.mp3", format="mp3")

Answer 2

Just sum as elements of a Python list:

sum(playlist_songs)
