Immich's Developers has specifically stated they're not interested in supporting audio recordings, which is really unfortunate (I didn't think I'd want this either until a few weeks ago when I heard my unborn baby's heartbeat for the first time).

I've been looking at Photoprism and it seems really close to what I want, but unsure - I think it'll be a case of pulling the trigger and giving it a go by quickly spinning up a container for it.

Regarding Moments, don't think I've heard of it, but from a quick search it may have been discontinued? Either way, I think the next step is to just experiment with something and see what fits.

Appreciate the input!
