Skirtu: Offline Stem Splitter

Remove vocals, drums or bass and play along with the rest of the song. Skirtu turns your audio files into practice tracks, directly on your iPhone. Every feature is free. There is no subscription. The optional support purchase unlocks no additional features. Split your song into vocals, drums, bass and other instruments. Solo a part to hear it clearly, mute it to practise along, or slow down and loop difficult sections. Your audio stays on your device, and no account is required. MADE FOR INSTRUMENT PRACTICE • Solo a part to study what it is playing • Mute your part and play along with the rest of the song • Slow playback from 0.50× to 1.25× without changing pitch • Loop difficult sections with A/B repeat • Jump backward or forward five seconds while learning VOCAL REMOVER AND KARAOKE Choose the No Vocals preset to create a karaoke-style backing mix. You can also remove drums or bass with one tap, or adjust the volume of each part. IMPORT AND EXPORT Import DRM-free MP3, M4A/AAC, WAV, AIFF and FLAC files up to 15 minutes long. Export your current mix as an M4A file at its original speed. PRIVATE BY DESIGN Separation happens on your iPhone. Your audio is not uploaded to a server. OPTIONAL SUPPORT If Skirtu helps you, you can optionally support development with a single, non-recurring in-app purchase. It does not unlock features or change how the app works. Source separation can leave faint sounds or artifacts, especially in complex mixes. “Other instruments” can include guitar, keys, strings and sounds not classified as vocals, drums or bass.
