Not a feature list padded out to look busy. This is everything Harmony does, each one finished enough to use, and each one shown here rather than promised.
The next track is open before the current one ends, and the padding MP3 and AAC encoders leave on the ends comes off — so a record cut to run together plays gapless, not nearly gapless. Crossfade and volume levelling when you want them, and your keyboard’s media keys already work.
Point Harmony at a folder and it reads every tag, track number and cover into a database on your own machine, then watches for whatever you add later. Search narrows from the first keystroke and stays that quick at 300,000 tracks, because the list only ever draws the rows you can see.
Bring every subscription across as OPML and take them out again the same way, the day you want to leave. Episodes download in the background, pick up where they left off if the connection drops, and remember the second you stopped listening.
Harmony looks the album up by its disc ID, reads each track carefully, goes back over anything the drive was unsure of, then checks the result against other people’s rips of the same disc before writing tagged FLAC into your library. There is nothing to install.
No. Harmony reads your folders where they are and writes nothing into them. The only files it ever creates are the ones you asked for — a CD rip, or a podcast episode — and both go where you tell them. Everything else it knows lives in its own database.
FLAC, ALAC, MP3, AAC, Ogg Vorbis, WAV and AIFF, at whatever sample rate your output device is running.
Only for the parts that are on the internet: podcast feeds and their episodes, and the album lookup when you rip a disc. Playing your own library never touches the network. A disc the lookup cannot find still rips — it just arrives with whatever the disc itself could tell us.
Not yet, and this is the honest gap. Podcast subscriptions come over as OPML, but playlists are made in Harmony rather than imported — there is no M3U reader. If that is what stands between you and using this, say so on the issue tracker, because it is the thing most likely to get built next.
Nothing happens to your music, because it was never Harmony’s to hold. The files are where you left them, in the folders you made, with the tags they came with. The database is a convenience; delete it and you have lost some playlists and a play count, not a collection.
