Version française : Sonodrill en français.

Sonodrill is an app to practice with audio, on iPhone and iPad. Import a song, a backing track or a recorded lesson, place marks where the sections start, then loop, skip and slow down exactly the parts you are working on.

• App Store: Sonodrill on the App Store — free, no ads, no in-app purchases.
• Code: git.schurger.org/sonodrill (Kotlin Multiplatform and Compose).

What it does

• Marks: placed while playing, named (Verse, Chorus, Solo…), adjusted by dragging.
• Loops: between two marks, over a whole section or over the entire track.
• Skip zones: jump over the parts you don't need, even inside a loop.
• Speed from 0.5× to 2× without changing the pitch, and transposition by semitones without changing the speed.
• Channels: left or right only, lowered center of the mix (often the voice), bass cut.
• Practice: delay before playing, metronome count-in, pause between passes, number of repetitions, and progressive speed that goes up at each pass.
• Sharing: marks export to a .sonodrill file to send to a teacher or a bandmate; they also sync between your devices through iCloud.
• Open audio from other apps (Files, Voice Memos, Mail…), background playback and lock screen controls.

No account, no data collected: your files stay on your device, only your marks go through your own iCloud. See the privacy policy.
