I recently learned that the wavepack audio codec can encode audio into lossy files with a second “correction” file that can be used during playback to regain full lossless quality of the source. This seems like a great option for those of us who love lossless audio, but also sometimes have trouble streaming the full fat FLAC files in our library over restrictive bandwidth limitations.
Here’s the codec project’s website for info.

On-the-fly conversion from flac to opus is something that even the smallest plex server can do fast enough nowadays. It happens fully automatically, depending on the bandwidth limitations you have set in the preferences of Plexamp.
This hybrid file approach is very much outdated.
That makes a lot of sense. I didn’t even know that plex transcoded audio for music. I think it would make a lot of sense for that to be a user controllable option like it is for video streaming. I have plexamp set to play full quality, but occasionally I run into network issues that forces my flac files to buffer.
It is a user-controlled preference. Just look into the settings of Plexamp.
