Manipulating multiple audio files with PyDub

You've seen how to convert a single file using PyDub but what if you had a folder with multiple different file types?

For this exercise, we've setup a folder which has .mp3, .m4a and .aac versions of the good-afternoon audio file.

We'll use PyDub to open each of the files and export them as .wav format so they're compatible with speech recognition APIs.

    # Read audio_file and export it in wav format
    AudioSegment.from_file(____).____(out_f=wav_filename, 
                                      format=____)
