So this is the case, my car an Alfa Romeo GT only plays 192kbps bitrate mp3 through an USB (other bitrates provoke artefacts at the speakers), and to play music first I must convert it to this specific file type. This was resulting in an tedious process where I was spending an average of 5 min to 10 min, to open the converter, setting the files, specifying the bitrate and then waiting to pass my music to the USB.

I love music and I was getting boring due to my music hadn’t changed so much since a year or two because I had to spent time doing conversions. So I wanted to create something fast and an automatic, like a Stradale.

Alfa Romeo 33 Stradale designed by Franco Scaglione, 1967

The first tool I needed was the converter something that would change all my music, the tool in this case is FFmpeg which is a command line tool that can convert, record and stream audio and video.

The next step was to create the script, at this time I was deciding between DOS, Python and PowerShell.

  • I didn’t want to spent much time learning a new language so Python was discarded.
  • I was very tempted to use PowerShell but a quick search on internet taught me that PowerShell doesn’t admit drag and drop files for security reasons, this was a big no.
  • So the decision was taken, to program it the arcane DOS language which I have very little experience with and to convert it later into a batch file.
