Unix subprocess.check_output compatibility

Please forgive my ignorance but I'm trying to get this working. When I run autosub -i myvideoFilter.wav

It immediately returns an error:

Convert source audio to "/var/folders/fz/_m3hd8n524x47ktcbwj4f6g00000gn/T/tmpq5j6nows.wav" and get audio length for regions detection.
ffmpeg -hide_banner -y -i "myvideoFilter.wav" -ac 1 -ar 48000 "/var/folders/fz/_m3hd8n524x47ktcbwj4f6g00000gn/T/tmpq5j6nows.wav"

At which stage is the file supposed to be generated?

It seems like a unix subprocess command issue. I will try to test it on an Ubuntu and do some research.

Commit f0ab2e1 should fix this issue. Thanks for your feedback.
