Adding music

Already have music as files? Drag an album folder anywhere onto the dashboard — the whole window becomes a drop target — or use browse files on your Mac’s device card to pick them. FLAC and MP3 are supported.

Cassette streams them straight to your Mac, lands them alongside your other music, and adds them to your library. You’ll see the progress right on the device card as it goes.

Away from your Mac when you drop something in? It’s held safely in your browser and uploads itself the moment your Mac is back online.

Put a disc in a connected drive and Cassette identifies it, then rips it to lossless FLAC. When the match is clear, one tap on “Rip to library” starts it; if it’s wrong, “Not this album?” lets you pick the right release.

You don’t have to wait around. The rip runs on your Mac in Cassette Player, not in your browser — you can close the page and come back, and it keeps going. If a rip is interrupted, the tracks that already finished are saved; starting again skips them rather than re-ripping the whole disc.

No disc drive? Any USB CD/DVD drive works — connect one and the rip controls appear on your Mac’s device card.

Your audio stays on your Mac, under ~/Music/Cassette/<Artist>/<Album>/ — it’s never uploaded to the cloud. What syncs is your library data: the albums you own, your plays, and your playlists, so your collection looks the same on every device.
