Probably a very niche use case, but I thought I would share my new project. It's an app that monitors an audio input and tries to identify what you are playing on your turntable. I use it with a Guiton screen to give a nice "Now Playing" display.
The blurb 
Vinyl Listener for Home Assistant A high-precision vinyl identification app.
Features Hybrid Identification: Attempts free local identification using Shazam first. Only falls back to ACRCloud if the track is not found, saving you API calls. You get 100 calls a day for the free level of ACRCloud.
Silence Detection: Automatically arms itself after the gap between tracks, preventing unnecessary API spam.
Automatic Album Art: Fetches high-res metadata and artwork via the iTunes API.
Recommended hardware to interface is a Behringer UCA222 USB Audio Interface

Installing the app is as simple as adding the URL to Repositories in Apps and looking for Vinyl Listener.
I hope this is of use to others. If anyone has any suggestions please feel free to make them!
