Well, the other side of the coin is that if you have two copies of the metadata, one in a MySQL database and the other in the file headers, then you need some mechanism to keep them synchronized. Otherwise you become the proverbial man with two watches who can never be sure what time it is.

IIRC, you can store a full complement of metadata in a WAV file and there is a standard for it, it's just not commonly done. I must admit that the one thing that has concerned me slightly is the fact that the ingested files are completely unidentifiable - the idea of writing out and

Of course, if you have the storage space and the horsepower, you could always export all the audio every so often... This puts a lot of the metadata into the files exported. Does it put it all? You can export to flac as well... all the best, drew On Tue, Nov 6, 2018 at 11:50 AM Rob Landry

Hi, Robert... It's heading that way. I indeed picked up a used machine for the current experiments and it should be fine for the application. Thankfully storage is cheap too: I have a 2TB drive on its way. I'll let rdimport ingest from the existing NTFS copy of the library and save its

Hi Richard, I would heartily recommend you build  a Rivendell system on a dedicated computer. You can source 2nd hand 64 bit machines relatively inexpensively and they work quite well. You may need to install a bigger drive for /var/snd depending on the music library size, but you can run
