Fixing open issues:

• Issue Folder path including non audio files #6 in commit 7626fd0
• Issue Model selector #7 in commit 6b6d453
• Issue Error logging #10 in commit 382b779

In addition, added support for the following:

• Better logging for GPU hardware failure
• Better error logging as WhisperX was complaining for the language setting

Looks good!

I suggested a modification to subprocess.run exception handling: catch subprocess.CalledProcessError instead of Exception (but backoff to Exception anyways).

Also ran linting (black + isort).

It's defiantly better this way. Thanks for the suggestion.
