Hokusai Audio Editor

Hokusai is a multitrack audio editor for iPhone, iPad or iPod touch. Record or import tracks, and make it sound the way you want it to: not just trimming the ends, but full cut, copy, paste and delete, and a suite of filters and special effects available.

Edit multiple tracks side-by-side, mix them together, and export to WAV or MP4 format. Design a clean, touch-friendly workflow with pinch-zoom, live scrubbing, and full undo/redo across sessions. The app ships with essential tools like fade in/out, normalize, and reverse, with optional in-app upgrades for advanced per-track controls, time-stretching, pitch-bending and a wide range of effects.
