How to transcode WAV to MP3 120k automatically on demand

[TheDreadPirate]

Here is what my server logs show when I have it set to 128Kbps for Internet Quality in Jellyfin on my Android phone.

Code:

If you are looking at the "Media Info" while you are playing back transcoded music, it will still show the original metadata.  Not the transcode metadata.

What are you seeing that makes you think you are receiving the raw WAV?
