Convert an audiofile with only the left channel to a two-channel audio file with ffmpeg.
When an audio file is only audible on one channel, it can be made stereo with ffmpg.
By creating a stereo output from mono, the same audio info will be placed in both channels and the channels will be identical.
Check if ffmpeg is installed on your machine:
$ ffmpeg -version ffmpeg version 3.4.2 Copyright (c) 2000-2018 the FFmpeg developers
If you do not have it, install from ffmpeg.org
Python users can use PIP install
pip install ffmpeg
Usage: Convert mono to stereo
ffmpeg -i mono.mp3 -ac 2 stereo.mp3
