What's New in Deconpose

1.1.0

October 16, 2026

Tempo, key, reach. • Tempo and key, automatically (iOS 27): after separating a song, Deconpose detects its BPM and key and shows them where you are: when the song changes tempo or key, the display follows, and the key follows the pitch control. The metronome clicks on the real beats, loops snap to the bar, and the count-in lands on the one. iOS 26 keeps tap tempo. • Song sections (iOS 27): the song's sections appear under the waveform. Tap one and exactly that part loops. • Zoom on the waveform: hold a finger on it to zoom in, so loop points and jumps land precisely even in long songs. • Bookmarks, faster: one tap sets one, and you name it afterwards. They sit in a bar under the waveform: tap one to jump there, even while the song plays. The editor moves a bookmark to the playhead or one beat at a time (iOS 27; otherwise in tenths of a second). • Keeps going while locked: separation continues when you lock your iPhone, with progress on the Lock Screen (Settings → Processing, can be switched off). • Song search: find songs to buy in the iTunes Store, right from the import sheet. Only your search term is sent to Apple, and only when you tap Search. Can be switched off. • Share to Deconpose: send audio files from Files or any other app straight to your library. • Siri & Shortcuts: "Open ‹song› in Deconpose", songs in Spotlight search. • Redeem codes under Settings → Account. • Now in Spanish and French.

How does Deconpose handle song imports?

Deconpose works with audio files you own, such as MP3, WAV, and M4A, imported from the Files app or your DRM-free music library. Streaming-only songs from services like Apple Music and Spotify cannot be imported due to copy protection.
