Error trying to use AudioSegment for .wav files

I'm trying to iterate through all the .wav files in a folder "audios", but I receive the following error. I found similar questions that were solved by installing ffmpeg, but that didn't help.

    FileNotFoundError                         Traceback (most recent call last)

          4

FileNotFoundError: [Errno 2] No such file or directory: 'name_of_file.wav'

Solution

os.listdir doesn't return the full paths of files in the directory you give it, just the names they have within that directory. You will need to prepend this directory name to the filename you pass to AudioSegment.from_wav.

Try replacing the line

     audio = AudioSegment.from_wav(audio_file)

with

     audio = AudioSegment.from_wav(os.path.join(base_path+"audios", audio_file))
