Is it possible, with or without a script, to send metadata when
an old-fashioned analog single or LP is played?
We're building an old-fashioned studio with CD players and turntables.
We're using mAirlist v7.
Yes this is possible. For Each Track you play, you need to manually add a silent element with the correct Title and Artist, and fire that seprately in mAirlist. You also can prepare this ahead in your database. One of my collegues put together a tool to donwload his Discogs collection and import it to mAirlist Database.
There is no way of fully automating this.
