A creative field recorder for iPhone.
Capture sound anywhere, process it through Collage on the phone, and keep every take organized.



Mural runs Collage presets and processor chains on the phone — browse the preset grid, open the rack, and process a field take the way you would in the studio.
What you capture in the field arrives ready to use in your session.


One tap, 16 or 24-bit, straight through the Collage engine or dry. Records with the screen off, survives calls, and drops markers that travel inside exports.
The same DSP as desktop Collage: 13 effect families with hundreds of variants, a drag-to-reorder signal path, the MORPH pad, and the DICE full-rack randomizer.
Trim with transient-snapping handles, ride pitch ±24 semitones live, slice into beat-detected loops, split a take into stems, clean up noise, and transcribe speech — all on-device.
Loops become pads with quantized switching, all running wet through Collage. Record the whole jam, and hold a pad to edit it mid-groove.
A loose inbox with one-tap stash, folders, search, and a take map. A chromatic tuner. Auto-mirror to Dropbox, Drive, or iCloud — and .kfx export straight to desktop Collage.
Everything runs on-device — stems, transcription, beat detection, all of it. No account, no upload, fully offline.
