failing after OS upgrade

[kraftydevil]

This is failing suddenly: $ transcribe speech voicefile.mp3

I did recently upgrade my OS (macOS 10.15.2) so I'm wondering if you can guess what might have broken based on the traceback.

  File "/usr/local/bin/transcribe", line 10, in <module>
    sys.exit(console())

The first thing I would try is to update pydub since the issue seems to originate there:

$ pip install -U pydub

And see if that fixes the problem.

If it doesn't, the next thing I would try is completely reinstalling transcribe (I'd get rid of the virtual environment or whatnot), it might have just been a hiccup with the os update somewhere, I've had that happen quite often with virtual environments after macOS updates or brew python updates.

Unfortunately, I'm not planning to upgrade to macOS 10.15 in the foreseeable future, but I'm not sure why the update would affect the code in any meaningful way either, so hopefully one of the above things will fix it.
