Hokusai is a multitrack audio editor for iPhone, iPad or iPod touch. Record or import a track, 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.

"Beautiful clutter-free interface" —

"Hokusai will convince you that audio was meant to be edited with a touch screen — it's just so natural within this app that you’ll find yourself consistently coming back to it." — iOS Music And You

Edit many tracks side-by-side, mix them together, and export to Wave or MP4 format — then transfer them to your computer, send them to another app on your device, or upload to cloud services.

Hokusai is streamlined to give you a clean, clear view of your tracks. Use the familiar pinch and swipe gestures to zoom right in and fiddle with fine detail, or step back to see the big picture. Select pieces of audio. Live "scrubbing" means you can hear the sound under your fingertip as you make your adjustments. And you needn't fear a bad edit with our full undo/redo support — even after closing your project.

Hokusai comes free with a set of useful tools such as fade in/out, normalise volume levels, reverse time, and basic synthesis. If you need more power, you can upgrade from inside the app to add new tools and effects, including: Per-track volume/mute/panning, selecting across multiple tracks at once, presets and favourites, grain synthesis, noise gating, time-stretching, pitch-bending, echo, reverb, modulation (AM & FM), resonance, distortion, grunge, vocal levelling, monster voice, high/low/band-pass/notch-cut filter and more — many of which can be previewed live.

Developer Response ,

Hello, sorry to hear that you have run into a problem. If you get in touch via the Contact Customer Support link inside the app, I can investigate it for you. If you can't reach that link due to the problem you're encountering, you can also get in touch via our website, which is linked from the App Store. Thanks!

Just a heads-up though, the version of iOS you're using on your iPhone is more than 30 versions out-of-date — we do try to maintain compatibility with older iOS versions, but future updates may not support versions of iOS that far back.

I had a problem with iMovie and mp3 files (probably too big). This is the first app that I have found after actually doesn’t need Apple Music or a computer to import. You can use the iCloud Drive. Perfect. You can edit by cropping (exactly what I needed). You can even send it anywhere.👍😀Finally. You don’t even need the full version for your basic needs. I’m pretty sure you can use it offline.
