SoXI failed with exit code 1

Question

I want to convert mp3 files to wav 16khz (these are files from Mozilla Common Voice)

My function

def one_sample(mp3_filename):
    """ Take an audio file, and optionally convert it to 16kHz WAV """
    if not os.path.splitext(mp3_filename.lower())[1] == ".mp3":
        mp3_filename += ".mp3"
    # Storing wav files next to the mp3 ones - just with a different suffix
    wav_filename = os.path.splitext(mp3_filename)[0] + ".wav"
    if not os.path.exists(wav_filename):
        transformer = sox.Transformer()
        transformer.convert(samplerate=SAMPLE_RATE, n_channels=CHANNELS)
        try:
            transformer.build(mp3_filename, wav_filename)
        except sox.core.SoxError:
            pass

I get an error for all files:

Traceback (most recent call last):
  File "C:\Users\Ksavich\AppData\Local\Programs\Python\Python38-32\lib\site-packages\sox\core.py", line 147, in soxi

During handling of the above exception, another exception occurred:

Process finished with exit code 1

I downloaded sox-14-4-2 and added it to the PATH And I use PyCharm

Well, you win for brevity, but that isn't the solution to why I'm getting the same error. – Wes Modes Dec 08 '21 at 01:38

Try running sox from the command line. It will give you more informative errors.

$ sox --i -c data/stereo-test.mp3

In my case, it told me I didn't have the libraries for mp3 files:

$ sox --i -c data/stereo-test.mp3 
sox FAIL formats: no handler for file extension `mp3'

On a Windows system, you'll have to install the correct DLLs.

On a linux system:

$ sudo apt-get install libsox-fmt-mp3

After that, I got more satisfying results:
