So is Roon essentially an aggregated digital library that supports all different audio file formats? I remember torrenting FLAC files by accident in my teens during high school but remember they weren’t supported in iTunes. So is Roon a library that can store MP3s, FLACs and more in one place? Is there a benefit of having Roon over just keeping all of your files on a hard drive that you can **theoretically** plug into your Bluesound and reference them from there? Not even sure if you can do the latter, just hypothesizing.
As
@Joe Mac said, the benefit is you can have your streaming + downloaded formats (pretty much any format...FLAC, MP3, WAV, etc) all as one cohesive library. It's a software solution, so you'd need the hardware side. It could be any number of options. The easiest/cheapest to start would probably just be on your desktop computer or a laptop. Whatever the device is, it needs to be powered on anytime you want to run Roon. This is called the Roon core. You select what folders you want it to index on there for your downloaded music library.
Then you just open the Roon app on your phone, select what you want your output to be (in your case it'd be the Node) and scroll through your library. It'll have all your indexed files from your harddrive or Rooncore PLUS all your favorites from Tidal or Qobuz. If there are duplicates (i.e. say you have one album as a downloaded MP3 but you also have it favorited in Tidal), I believe Roon will autoselect whichever is higher quality. Or if you prefer your local download, you can set that as the preferred version of the album. Any time you add new songs or albums to your local library, or favorite an album in Tidal, it will update the software library automatically. Searching in Roon will search your local download library + streaming service in one go.
There are tons of features. You can do multi-room audio with Roon-ready or Roon-tested devices. You can sort by just about every possible category of metadata--so you can show only your FLAC files, or only your DSD files, etc. You can also filter by composer/artist and I think even stuff like dynamic range.
It keeps track of your top artists, top albums, listening time, favorite genres, etc. It recommends new releases, has album reviews built in, etc.
To get an idea of the full uses and features, I'd say set aside some time on a weekend or one night to set up a temporary Roon core on a computer, have your downloaded files all in one location and try the 30 day trial. I hated the proprietary OS on my streamer and found it was annoying to listen to stream music. I use Qobuz primarily so didn't have Tidal Connect. I did a trial of Roon and never looked back.
