Exporting and reformatting audio files
If you've made some changes to your audio files, or if they've got the wrong file extension, you can use PyDub
to export and save them as new audio files.
You can do this by using the .export()
function on any instance of an AudioSegment
you've created. The export()
function takes two parameters, out_f
, or the destination file path of your audio file and format
, the format you'd like your new audio file to be. Both of these are strings. format
is "mp3"
by default so be sure to change it if you need.
In this exercise, you'll import this .mp3
file (mp3_file.mp3
) and then export it with the .wav
extension using .export()
.
Remember, to work with files other than .wav
, you'll need ffmpeg.
This is a part of the course
